XD-1103: Reinstate JDBC sink DataSource

Since the big Bootification the jdbc sink has been sharing
a DataSource with the parent context. This change re-instates
the local version (using Boot features).

Also resets initializeDatabase to default to true which was the
cause of the original issue.
Reinstate rabbit module connection factories

Similar to the JDBC sink datasource, bootification original removed
these. This commit adds the individual module configurations back.
