This change adds a `coco plan` command which is simply a shortcut to the more verbose `coco deploy --dry-run`. This will make demos flow nicer and elevates planning, an important activity, to a more prominent position. The `--dry-run` (aka `-n`) flag is still there. This change also renames `coco env destroy` to just `coco destroy`. This is consistent with deploy and plan being at the top-level. We now use `coco env` purely for evironment management commands (init, config, rm, etc).
