Functional gate broken due to configure_for_func_testing.sh inability to configure DB backends

[Assaf Muller]

After https://review.openstack.org/#/c/233106/ was merged to Devstack, the configure_for_func_testing.sh script is unable to configure both DB backends, and test setup eventually fails as such:

This happens because the Postgres disable is successful, but the Postgres enable is ignored by Devstack. The issue is here:

    Remove disable_service from DBs configuration

    Remove disable_service from configure_for_func_testing.
    A recent Devstack patch (Linked in bug report) checks
    that a disabled service is not enabled later. This breaks
    the code this patch touches. I believe the DBs were disabled
    and enabled with the assumption that Devstack expects only
    a single DB to be configured at a time, but that doesn't
    seem to be the case. Simply removing the disable calls seems
    to work fine.

    Also exclude oslo.messaging==2.6.0 as per global-requirements.txt.
