make crawlTimeout a per-crawconfig property

allow crawl complete/partial complete to update existing crawl state, eg. timeout
enable handling backofflimitexceeded / deadlineexceeded failure, with possible success able to override the failure state
filter out only active jobs in running crawls listing
