Bug 1306578 - Use retryable_task for pulse job ingestion

Was calling retry manually, but that was causing repeated
retries that were blowing up the celery queue.  This just
uses our normal retryable_task for retries and adds some
extra logging in new relic to help identify the product
of a pulse job that failed.
