    Make association_refresh configurable
    
    The provider-tree refresh in the SchedulerReportClient() instance
    of each compute node happens every five minutes as it is hard coded.
    This patch adds this update interval as a new config option which
    can be set/changed on each compute node.

Title:
  Placement - Make association_refresh configurable

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) queens series:
  Triaged

Bug description:
  In Queens the provider-tree refresh happens every 5 min (also in master).
  ASSOCIATION_REFRESH = 300

  For large deployments this creates unnecessary load in placement.
  This option should be configurable.
