Title:
  ironic: power sync loop makes way too many API calls

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) rocky series:
  In Progress

Bug description:
  The ironic driver does not use its local cache of node data for the
  get_info call, which is used during the instance power sync. This
  results in N API calls per power sync loop, where N is the number of
  instances managed by the compute service doing the sync.

  We should aim to use the cache and reduce this to one or less API
  calls.
