    DB migration tests

    Refactored migration tests to use OpportunisticTestCase, removed
    unused code and ``test_migrations.conf`` file.

    The main feature of this approach is to create a new database with
    random name for each migration test. This will avoid migration tests of
    race conditions and reduce tests intersection. After this change, database
    ``openstack_citest`` will be used only for initial connection to the database.

    ``test_migrations.conf`` file not required anymore, because we create test
    database for migration test, so we no longer need to keep database credentials.

    Implements blueprint: db-migration-tests
