Introduce destroy command

[VOVELEE]

Details

Currently branch-deploy supports noop and deploy commands and this works great.
In order to manage complete lifecycle of deployments - will it be possible to introduce destroy command?

@VOVELEE I could certainly see this being added as a feature. Here are some questions to expand upon this:

• How would you expect this to work or to be used in detail?
• Would you want the command to be named .delete or .destroy by default?
• Should the "destroy" command trigger a new deployment event to a given environment (the little green rocket) or should it not create one since it is removing resources? I would imagine it should be treated as a deployment event (even though it is removing things) so the branch protection rules that are configured for a project (requiring deployments) would still allow merges - After all, it is still a deployment, just one that involves the removal of something.

Under the hood, I would imagine this new feature to work almost identically to the .noop command. It would just set slightly different outputs so users could conditionally run different steps in their workflows. It would also create a deployment event.
