Title:
  nova-scheduler also loads deleted instances at startup

Status in OpenStack Compute (nova):
  In Progress

Bug description:
  nova-scheduler is loading all instances (including deleted) at
  startup.

  Experienced problems when each node has >6000 deleted instances, even when using batches of 10 nodes.
  Each query can take several minutes and transfer several GB of data.
  This prevented nova-scheduler connect to rabbitmq.

  
  ###
  When nova-scheduler starts it calls "_async_init_instance_info()" and it does an "InstanceList.get_by_filters" that uses batches of 10 nodes. This uses "instance_get_all_by_filters_sort", however "Deleted instances will be returned by default, unless there's a filter that says otherwise".
  Adding the filter: {"deleted": False} fixes the problem.
