Rotating a passphrase requires that the old passphrase is available via
one of the `PULUMI_CONFIG_PASSPHRASE` or `PULUMI_CONFIG_PASSPHRASE_FILE`
environment variables. This confuses `readPassphrase` when reading a new
passphrase, since that function checks the aforementioned environment
variables prior to reading from the console. The overall effect is that
it is impossible to rotate the passphrase for a stack using the
passphrase provider. These changes fix this by always reading from the
console when rotating a passphrase.
When using the filestate backend (local files and cloud buckets) there is no protection to prevent two processes from managing the same stack simultaneously.
This PR creates a locks directory in the management directory that stores lock files for a stack. Each backend implementation gets its own UUID that is joined with the stack name. The feature is currently available behind the `PULUMI_SELF_MANAGED_STATE_LOCKING=1` environment variable flag.
The PULUMI_BACKEND_URL env var allows specifying the backend to use instead of deferring to the project or the ~/.pulumi/credentials.json file to decide on the "current" backend. This allows for using Pulumi without a dependence on this piece of global filesystem state, so that each `pulumi` invocation can control the exact backend it want's to operate on, without having to do stateful `pulumi login`/`pulumi logout` operations.
This is especially useful for automation scenarios like Automation API generally (and effectively solves https://github.com/pulumi/pulumi/issues/5591), or https://github.com/pulumi/pulumi-kubernetes-operator/issues/83 specifically.
This also makes things like efe7a599e6/dist/actions/entrypoint.sh (L10) less necessary, and possible to accomplish for any containerized `pulumi` execution without the need for this logic to be embedded in bash scripts wrapping the CLI.
