Add "redeploy" option for individual servers

[jesse-gallagher]

This could be used as essentially a cleaning operation if, for example, the dropins content drifts from what's in the NSF. It should outright delete the server (using the batch file) and redeploy from the NSF.

This will require a hook back in the provider service to tell it that the server was cleaned, so it can re-contribute applicable WARs.
