Repivot plan/apply commands; prepare for updates
This change repivots the plan/apply commands slightly. This is largely
in preparation for performing deletes and updates of existing environments.
The old way was slightly confusing and made things appear more "magical"
than they actually are. Namely, different things are needed for different
kinds of deployment operations, and trying to present them each underneath
a single pair of CLI commands just leads to weird modality and options.
The new way is to offer three commands: create, update, and delete. Each
does what it says on the tin: create provisions a new environment, update
makes resource updates to an existing one, and delete tears down an existing
one entirely. The arguments are what make this interesting: create demands
a MuPackage to evaluate (producing the new desired state snapshot), update
takes *both* an existing snapshot file plus a MuPackage to evaluate (producing
the new desired state snapshot to diff against the existing one), and delete
merely takes an existing snapshot file and no MuPackage, since all it must
do is tear down an existing known environment.
Replacing the plan functionality is the --dry-run (-n) flag that may be
passed to any of the above commands. This will print out the plan without
actually performing any opterations.
All commands produce serializable resource files in the MuGL file format,
and attempt to do smart things with respect to backups, etc., to support the
intended "Git-oriented" workflow of the pure CLI dev experience.

Make major commands more pleasant
This change eliminates the need to constantly type in the environment
name when performing major commands like configuration, planning, and
deployment. It's probably due to my age, however, I keep fat-fingering
simple commands in front of investors and I am embarrassed!
In the new model, there is a notion of a "current environment", and
I have modeled it kinda sorta just like Git's notion of "current branch."
By default, the current environment is set when you `init` something.
Otherwise, there is the `coco env select <env>` command to change it.
(Running this command w/out a new <env> will show you the current one.)
The major commands `config`, `plan`, `deploy`, and `destroy` will prefer
to use the current environment, unless it is overridden by using the
--env flag. All of the `coco env <cmd> <env>` commands still require the
explicit passing of an environment which seems reasonable since they are,
after all, about manipulating environments.
As part of this, I've overhauled the aging workspace settings cruft,
which had fallen into disrepair since the initial prototype.

Improve the overall cloud CLI experience
This improves the overall cloud CLI experience workflow.
Now whether a stack is local or cloud is inherent to the stack
itself. If you interact with a cloud stack, we transparently talk
to the cloud; if you interact with a local stack, we just do the
right thing, and perform all operations locally. Aside from sometimes
seeing a cloud emoji pop-up ☁️, the experience is quite similar.
For example, to initialize a new cloud stack, simply:
$ pulumi login
Logging into Pulumi Cloud: https://pulumi.com/
Enter Pulumi access token: <enter your token>
$ pulumi stack init my-cloud-stack
Note that you may log into a specific cloud if you'd like. For
now, this is just for our own testing purposes, but someday when we
support custom clouds (e.g., Enterprise), you can just say:
$ pulumi login --cloud-url https://corp.acme.my-ppc.net:9873
The cloud is now the default. If you instead prefer a "fire and
forget" style of stack, you can skip the login and pass `--local`:
$ pulumi stack init my-faf-stack --local
If you are logged in and run `pulumi`, we tell you as much:
$ pulumi
Usage:
pulumi [command]
// as before...
Currently logged into the Pulumi Cloud ☁️
https://pulumi.com/
And if you list your stacks, we tell you which one is local or not:
$ pulumi stack ls
NAME LAST UPDATE RESOURCE COUNT CLOUD URL
my-cloud-stack 2017-12-01 ... 3 https://pulumi.com/
my-faf-stack n/a 0 n/a
And `pulumi stack` by itself prints information like your cloud org,
PPC name, and so on, in addition to the usuals.
I shall write up more details and make sure to document these changes.
This change also fairly significantly refactors the layout of cloud
versus local logic, so that the cmd/ package is resonsible for CLI
things, and the new pkg/backend/ package is responsible for the
backends. The following is the overall resulting package architecture:
* The backend.Backend interface can be implemented to substitute
a new backend. This has operations to get and list stacks,
perform updates, and so on.
* The backend.Stack struct is a wrapper around a stack that has
or is being manipulated by a Backend. It resembles our existing
Stack notions in the engine, but carries additional metadata
about its source. Notably, it offers functions that allow
operations like updating and deleting on the Backend from which
it came.
* There is very little else in the pkg/backend/ package.
* A new package, pkg/backend/local/, encapsulates all local state
management for "fire and forget" scenarios. It simply implements
the above logic and contains anything specific to the local
experience.
* A peer package, pkg/backend/cloud/, encapsulates all logic
required for the cloud experience. This includes its subpackage
apitype/ which contains JSON schema descriptions required for
REST calls against the cloud backend. It also contains handy
functions to list which clouds we have authenticated with.
* A subpackage here, pkg/backend/state/, is not a provider at all.
Instead, it contains all of the state management functions that
are currently shared between local and cloud backends. This
includes configuration logic -- including encryption -- as well
as logic pertaining to which stacks are known to the workspace.
This addresses pulumi/pulumi#629 and pulumi/pulumi#494.

Make major commands more pleasant
This change eliminates the need to constantly type in the environment
name when performing major commands like configuration, planning, and
deployment. It's probably due to my age, however, I keep fat-fingering
simple commands in front of investors and I am embarrassed!
In the new model, there is a notion of a "current environment", and
I have modeled it kinda sorta just like Git's notion of "current branch."
By default, the current environment is set when you `init` something.
Otherwise, there is the `coco env select <env>` command to change it.
(Running this command w/out a new <env> will show you the current one.)
The major commands `config`, `plan`, `deploy`, and `destroy` will prefer
to use the current environment, unless it is overridden by using the
--env flag. All of the `coco env <cmd> <env>` commands still require the
explicit passing of an environment which seems reasonable since they are,
after all, about manipulating environments.
As part of this, I've overhauled the aging workspace settings cruft,
which had fallen into disrepair since the initial prototype.

Implement `get` functions on all resources
This change implements the `get` function for resources. Per pulumi/lumi#83,
this allows Lumi scripts to actually read from the target environment.
For example, we can now look up a SecurityGroup from its ARN:
let group = aws.ec2.SecurityGroup.get(
"arn:aws:ec2:us-west-2:153052954103:security-group:sg-02150d79");
The returned object is a fully functional resource object. So, we can then
link it up with an EC2 instance, for example, in the usual ways:
let instance = new aws.ec2.Instance(..., {
securityGroups: [ group ],
});
This didn't require any changes to the RPC or provider model, since we
already implement the Get function.
There are a few loose ends; two are short term:
1) URNs are not rehydrated.
2) Query is not yet implemented.
One is mid-term:
3) We probably want a URN-based lookup function. But we will likely
wait until we tackle pulumi/lumi#109 before adding this.
And one is long term (and subtle):
4) These amount to I/O and are not repeatable! A change in the target
environment may cause a script to generate a different plan
intermittently. Most likely we want to apply a different kind of
deployment "policy" for such scripts. These are inching towards the
scripting model of pulumi/lumi#121, which is an entirely different
beast than the repeatable immutable infrastructure deployments.
Finally, it is worth noting that with this, we have some of the fundamental
underpinnings required to finally tackle "inference" (pulumi/lumi#142).

Repivot plan/apply commands; prepare for updates
This change repivots the plan/apply commands slightly. This is largely
in preparation for performing deletes and updates of existing environments.
The old way was slightly confusing and made things appear more "magical"
than they actually are. Namely, different things are needed for different
kinds of deployment operations, and trying to present them each underneath
a single pair of CLI commands just leads to weird modality and options.
The new way is to offer three commands: create, update, and delete. Each
does what it says on the tin: create provisions a new environment, update
makes resource updates to an existing one, and delete tears down an existing
one entirely. The arguments are what make this interesting: create demands
a MuPackage to evaluate (producing the new desired state snapshot), update
takes *both* an existing snapshot file plus a MuPackage to evaluate (producing
the new desired state snapshot to diff against the existing one), and delete
merely takes an existing snapshot file and no MuPackage, since all it must
do is tear down an existing known environment.
Replacing the plan functionality is the --dry-run (-n) flag that may be
passed to any of the above commands. This will print out the plan without
actually performing any opterations.
All commands produce serializable resource files in the MuGL file format,
and attempt to do smart things with respect to backups, etc., to support the
intended "Git-oriented" workflow of the pure CLI dev experience.
