operator: set elapsed and exec time in operator from db

[ikreymer]

• already updating db with exec time
• also increment elapsed time in db
• set the CrawlJob status exec and elapsed time values from the db

It looks like the new 0 value here is causing the tests to fail, and we are now getting qaCrawlExecSeconds as 0:

    def test_qa_org_stats(
        qa_crawl_id, crawler_auth_headers, default_org_id, qa_run_pages_ready
    ):
        r = requests.get(
            f"{API_PREFIX}/orgs/{default_org_id}/crawls/{qa_crawl_id}",
            headers=crawler_auth_headers,
        )
        crawl_stats = r.json()
>       assert crawl_stats["qaCrawlExecSeconds"] > 0
E       assert 0 > 0
