Bulk save facts, and move to before status change (#12998)

* Facts scaling fixes for large inventory, timing issue

Move save of Ansible facts to before the job status changes
  this is considered an acceptable delay with the other
  performance fixes here

Remove completely unrelated unused facts method

Scale related changes to facts saving:
  Use .iterator() on queryset when looping
  Change save to bulk_update
  Apply bulk_update in batches of 100, to reduce memory
  Only save a single file modtime, avoiding large dict

Use decorator for long func time logging
  update decorator to fill in format statement
