Refactor much of the special logic for CloudMan and GalaxyVmLauncher out of core of deployer framework and into a new plugin structure. Though less straight-forward, I think this new structure is more extensible and cleaner.
Galaxy: Allow expansion __contrib_dir__ when looking for Galaxy tools file (galaxy_tool_conf).
Proteomics: Add deployer settings file sample for Galaxy-P. This is probably too specific, I don't want to recreate flavors as settings.yaml samples, so I eventually will just make this Galaxy and add special instructions on getgalaxyp.org for how to tweak it for Galaxy-P.
