Matt Ellis 22c9e0471c Use `Stack` over `Environment` to describe a deployment target ... Previously we used the word "Environment" as the term for a deployment target, but since then we've started to use the term Stack. Adopt this across the CLI. From a user's point of view, there are a few changes: 1. The `env` verb has been renamed to `stack` 2. The `-e` and `--env` options to commands which operate on an environment now take `-s` or `--stack` instead. 3. Becase of (2), the commands that used `-s` to display a summary now only support passing the full option name (`--summary`). On the local file system, we still store checkpoint data in the `env` sub-folder under `.pulumi` (so we can reuse existing checkpoint files that were written to the old folder)		2017-10-16 13:04:20 -07:00
