This RFE is to track Satellite 6 support for hosting the Postgres and Mongo databases on systems other than the Satellite itself. 

Satellite 6 should support a user scenario:

1) User procures a machine which has postgres installed on it
2) User procures a second (or the same) machine which has mongo on it
3) Satellite is installed on a third machine, and the installer takes care of installing on those external machines
4) backup and restore scripts use pg dump and mongo like equivilance.
