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.
