Document caveats around ps:rebuild and tags/tar deployed applications. Closes #2374

Browse Source 
The tags and tar plugins do not necessarily build from source, and running `ps:rebuild` can have some unexpected output in certain cases. Rather than try to handle that complexity - it's a lot - documenting the edge cases is the most appropriate way forward.

### Restarting applications
Applications can be restarted, which is functionally identical to calling the `release_and_deploy` function on an application. Please not that any linked containers *must* be started before the application in order to have a successful boot.
