Since I4fdf7f7 more code stops returning the implementation, but only
returns the interface. This is a good, very welcome change. However,
ConnectionManager still requires the LoadBalancer implementation, for
no obvious reason. All code in this class works fine with the interface.
This is currently reported by Phan as a violation (and it actually is
one), e.g.:

Redundant given this is the project-wide license already,
especially in file headers that already include the GPL license
header.
This and other minor fixups based on feedback from Ie0cea0ef5027c7e5.
* Add @file where missing.
* Move @ingroup and @deprecated from file to class doc where needed.

This moves and refactors the ConsistentReadConnectionManager
from Wikibase into the core rdbms lib.
The refactoring also creates a generic ConnectionManager.
This relates to Iff20a22f9f2bc7ceefd6defc0ed9a494a6fe62c0
which introduced a DB factory / connection manager in
an extension revealing the need for this in multiple places.
