Bug description:
  *Descrption:
    ** We observed neutron_ovn_metadata_agent was stuck when connection ovn_sb_db is reset
    ** After investigation, we found that MetadataAgent.register_metadata_agent keeps retrying infinitely due to an unrecoverable error in this line: chassis_id = uuid.UUID(self._get_own_chassis_name()). This block the thread for RowEventHandler.notify_loop.
    ** The neutron is deployed by kolla ansible, where chassis name returned here is the hostname of the compute nodes, and it is not recognized as a valid UUID.

  * Version:
    ** OpenStack Xena
    ** Ubuntu focal 20.04
    ** Kolla Ansible
