    INFO level logging should be useful in resource tracker
    
    Rather than log messages such as "Starting to do work" at INFO level,
    these should be logged at DEBUG level.  Useful information, such as the
    final resource view, should continue to be logged at INFO.

Title:
  Resource tracker logs at too high level

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  There are very few INFO messages logged by periodic tasks, but every
  minute the resource tracker logs 4 lines, for example:

  <182>Nov 17 13:26:24 node-4 nova-compute: 2016-11-17 13:26:24.942 1143 INFO nova.compute.resource_tracker [req-85a43595-8d23-4f5f-bfb2-59689d3b873f - - - - -] Auditing locally available compute resources for node xrtmia-03-01

  <182>Nov 17 13:26:25 node-4 nova-compute: 2016-11-17 13:26:25.789 1143 INFO nova.compute.resource_tracker [req-85a43595-8d23-4f5f-bfb2-59689d3b873f - - - - -] Compute_service record updated for node-4.domain.tld:xrtmia-03-01

  Of these 4 lines, only one is useful at the INFO level; the one reporting the final resource view.
  The other three log lines should be reduced to DEBUG level as they are generally not useful to be logged in normal operation.
