We want to enable Cloudify Manager & the Postgres DB reside on separate machines.
cfy_manager will now look for the values of these keys in config.yaml:
If the value of host is not "localhost", "cfy_manager install" will try to connect to the external Postgres, with the given credentials, and instantiate the DB.
Based on the list given in "services_to_install", "cfy_manager install" will install only the desired services.
In case 'database_service' is chosen, the 'enable_remote_connections' should be set to true
Due to this change in architecture, right now clustering will not be supported with an external database.
This will be addressed in a future release
