Update git submodules

* Update oslo.db from branch 'master'
  - Rollback existing nested transacvtion before restarting
    
    SQLAlchemy 1.4 will be adding stricter rules to Connection objects
    such that a new transaction cannot be started while an old one hasn't
    been cleared.   Ensure this particular test fixture clears
    the "savepoint" transaction first before starting a new one.
