test_sql_upgrade docstring needs update

[Rodrigo Duarte]

Currently, the docstring at [1] states the usage of the backend_sql.conf file, which isn't used anymore in the tests of the module. Instead, the tests are using oslo.db unit tests base [2]. This doesn't mean the backend_sql.conf file isn't used anywhere else, but that it is not used anymore at test_sql_upgrade.

    Updated docstring for test_sql_upgrade.py

    The docstring at [1] references usage of backend_sql.conf, which is no
    longer used by the tests. The tests are using oslo.db unit tests base.
    This patchset updates the docstring and places a reference to [2].
