This change includes a handful of stack-related CLI formatting
improvements that I've been noodling on in the background for a while,
based on things that tend to trip up demos and the inner loop workflow.
This includes:
* If `pulumi stack select` is run by itself, use an interactive
CLI menu to let the user select an existing stack, or choose to
create a new one. This looks as follows
$ pulumi stack select
Please choose a stack, or choose to create a new one:
abcdef
babblabblabble
> currentlyselected
defcon
<create a new stack>
and is navigated in the usual way (key up, down, enter).
* If a stack name is passed that does not exist, prompt the user
to ask whether s/he wants to create one on-demand. This hooks
interesting moments in time, like `pulumi stack select foo`,
and cuts down on the need to run additional commands.
* If a current stack is required, but none is currently selected,
then pop the same interactive menu shown above to select one.
Depending on the command being run, we may or may not show the
option to create a new stack (e.g., that doesn't make much sense
when you're running `pulumi destroy`, but might when you're
running `pulumi stack`). This again lets you do with a single
command what would have otherwise entailed an error with multiple
commands to recover from it.
* If you run `pulumi stack init` without any additional arguments,
we interactively prompt for the stack name. Before, we would
error and you'd then need to run `pulumi stack init <name>`.
* Colorize some things nicely; for example, now all prompts will
by default become bright white.
