When we create amphora for specific loadbalancer it would be
good to get info about mapping pair loadbalancer-amphora as
soon as possible.
For example, if admin needs to debug connectivity issues with amphora
VMs - loadbalancer_id won't be set until AmphoraComputeConnectivityWait
task succeeds (which is never for such case) so they have to go to worker
logs to understand which amphora is related to a currently creating
loadbalancer.
