    [OVN] Fix ML2/OVN + Neutron DHCP agent use case

    In an attempt to minimize the number of connections to the OVSDBs the
    ML2/OVN driver stopped connecting to the OVN dbs if the Neutron worker
    was a RpcWorker but, that introduced a regression for those using
    ML2/OVN + Neutron DHCP agent (for baremetal provisioning).

    Because the RpcWorker didn't have a connection to the OVN database the
    Neutron DHCP agent wasn't able to create the DHCP port and failed with:

    2021-07-13 13:36:18.116 17 ERROR neutron.plugins.ml2.managers if not
    self._sb_ovn.chassis_exists(host):
    2021-07-13 13:36:18.116 17 ERROR neutron.plugins.ml2.managers
    AttributeError: 'NoneType' object has no attribute 'chassis_exists'

    This patch adds the RpcWorker back to the list of workers that should
    connect to the OVN databases.
