This is due to the code is using log.isEnabledFor() but neutron does not update oslo-incubate for the log utility, and in current neutron.openstack.common.log, there is not isEanabledFor

    Remove the log.isEnabledFor check as neutron log is not support yet

    Remove the log.isEnabledFor in message.py as neutron does not sync the
    oslo-incubate as nova's level, there is no isEnabledFor at this time in
    neutron openstack.common.log.
