Title:
  n-cond shoul not joining to servicegroup an all worker

Status in OpenStack Compute (nova):
  Expired

Bug description:
  All nova conductor worker process attempts to join to the service on the same host. It does not seams required.
  If you have 48 conductor worker on a node, it means it tries to maintain the membership with all 48 worker.

  Since the workers are started almost at the same time, it means 48
  burst update attempt close to each other.

  The situation even worse with zk driver,  it does not works with multiple workers >1 , because all worker thread inherited the same zookeeper connection from it's parent.  (4096 connection allowed from the same ip on my zk servers)
  (The api service does not do status report, so it can work with multiple workers)

  The  "lsof -P |grep cond | grep 2181"  indicates all conductor worker
  uses the same tcp source port  --> the same socket inherited.
