    Don't crash ovs agent during reconfigure of phys bridges
    
    In case when physical bridge was recreated on host, ovs agent
    is trying to reconfigure it.
    If there will be e.g. timeout while getting bridge's datapath_id,
    RuntimeError will be raised and that caused crash of whole agent.
    
    This patch changes that to not crash agent in such case but try to
    reconfigure everything in next rpc_loop iteration once again.

Title:

Status in neutron:
  Fix Released

Bug description:
  In case when e.g. bridge was recreated ovs-agent has to reconfigure it
  and in such case if there will be timeout while getting bridge data
  path id whole ovs agent will crash.

  It causes failure of fullstack tests like e.g.: http://logs.openstack.org/81/671881/1/check/neutron-fullstack/c6b2e08/testr_results.html.gz
  see agent's logs: http://logs.openstack.org/81/671881/1/check/neutron-fullstack/c6b2e08/controller/logs/dsvm-fullstack-logs/TestLegacyL3Agent.test_north_south_traffic/neutron-openvswitch-agent--2019-07-22--07-48-17-892074_log.txt.gz#_2019-07-22_07_49_28_698
