SQLAlchemy 1.3 has deprecated engine.contextual_connect() which
will be removed in 1.4. Additionally, private methods like
Engine._run_visitor will also be removed.

Since ibm_db_sa is not part of sqlalchemy, we need to handle the
conditional import of the module in visitor.py so we don't get an
ImportError if ibm_db_sa is not available.

This patch adds the initial support for DB2 10.5 to migrate. It
includes:
1. The dialect implementation for DB2.
2. The dialect registration with the visitor.
3. Code to parse the engine name in version.py.
4. A new dependency on ibm_db_sa in test-requirements.txt.
5. A connection string in test_db.cfg for ibm_db_sa.
