Rework `morph deploy` to work with cluster morphologies.

From now on, `morph deploy` will work to only accept a cluster
morphology as argument. A cluster morphology defines a list of
systems to built, and for each system a list of ways to deploy
them. We will not support the old syntax anymore.

- Update `morph deploy` docstring with the new syntax, including
  an explanation of cluster morphologies (also document `tar`
  deployments).
- Fix tests that used the old syntax.
- Add tests for cluster deployments.
