Takashi Kajinami 6b93ecf0e1 Refactor resource dependencies
This refactors resource dependencies to improve the following points.

 - Avoid unnecessary dependencies across services. For example aodh
   service does not require cinder db.

 - Restart only api service when config files like paste.ini, which
   are used only be api service is changed.

Also, guestagent.conf is not used by trove services but the overall
file is loaded each time when trove launches an instance, so we don't
have to restart trove services when guesagent.conf is updated.
