Bug description:
  When SIGHUP signal is send to nova-api service, it doesn't complete
  processing of all pending requests before terminating all the
  processes.

  Steps to reproduce:

  1. Run nova-api service as a daemon.
  2. Send SIGHUP signal to nova-api service.
     kill -1 <parent_process_id_of_nova_api>

  After getting SIGHUP signal all the processes of nova-api stops instantly, without completing existing request, which might cause failure.
  Ideally after getting the SIGHUP signal nova-api process should stop getting new requests and wait for existing requests to complete before terminating all the processes and restarting all nova-api processes.
