If an Octavia loadbalancer is stuck in PENDING_UPDATE state or Neutron port is DOWN despite being plugged there's not much Kuryr can do. For such cases we need to clearly message the user that the error they're seeing is caused by OpenStack service misbehaving and not Kuryr. This commit does so by making sure in such cases we raise a distinct version of ResourceNotReady exception. Change-Id: I2dd1e8989caf004b3dee0cb51780a45ce8d9353c Closes-Bug: 1918711
