    Networking-ovn gate failed for ovn-controller service error.

    Another problem is regarding the commit
    d0c961a99f570ec1973bf5540ba9237b6720c848 from OVS that removed the
    run, log, and db directories as part of the normal `make install`
    process. These directories were expected to be in place, so this patch
    is manually creating them before the DevStack module for networking-ovn
    tries to set some permissions on them.
