MB-269 #Created a single Postgres container for all APIs.

Each API gets it's own database created. This way if/when we need to split databases to different servers in production as demand grows, it becomes easy to move them.
MC-101 #Updated Config DB to reflect the new API changes.
MB-136 #Reverted 'metering' to 'monitoring'
MC-64 #Bugfix: get_service_configs

The method was returning the entire config for the host that the service was run on. This was fine when running one service per host, but otherwise would return a lot of unrelated data. The query has been limited to the config of only the specified service.
