ARTEMIS-1653 Allow database tables to be created externally

The previous commit about this feature wasn't using the row count query
ResultSet.
The mechanics has been changed to allow the row count query
to fail, because DROP and CREATE aren't transactional and immediate
in most DBMS.
It includes a test that stress its mechanics if used with DBMS like
DB2 10.5 and Oracle 12c.
Additional checks and logs have been added to trace each steps.

> In some environments (e.g. production) it is not allowed that applications 
> create their own schema. It's common practice to pass DDL-Statetements to 
> DBAs instead prior to rollout.
> Currently the broker does not support this scenario. If the required tables 
> already exist the broker fails to start.
> A better approach is that if the broker detects empy tables and initializes 
> them in the very same way it does if the tables dont't exist.
