Database configuration for (proto)cells

We need to decide on how we configure database(s) for Cells.

The options are:

1. Single logical database
2. Multiple logical databases (main/ci/sec)

groupdatabase frameworks recommends option 2 as the app is already handling this and it leaves the door open if we ever have to split the databases into multiple clusters. With option 1 we will have to go through the same procedure we had to do for decomposition switchover.
