    Move hash ring initialization to init_host() for ironic
    
    The hash ring initialization code requires calling to conductor over
    RPC. Nova's service startup initializes the manager and the virt
    driver, then goes into a polling loop waiting for a conductor to
    respond to make sure it is ready. Finally, it calls init_host()
    once things are expected to be working. That is where we should
    do our initialization that requires conductor to be up.
    
    This patch moves the initial refresh into the Ironic driver's
    init_host() routine.

Title:
  Nova compute driver init happens before conductor is ready

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  In nova/service.py we poll for conductor readiness before we allow
  normal service startup behavior. The ironic driver does RPC to
  conductor in its _refresh_hash_ring() code, which may expect conductor
  be up before it's not. If so, we'll fail to start up because we called
  to conductor, waited a long time, and then timed out.
