* crawl queue api work: (#329)
- add api to /crawls/{crawl_id}/queue api to get crawl queue, with offset, count, and optional regex. returns results and regex matches within the results, along with total urls in queue.
- add api to match entire crawl queue, /crawls/{crawl_id}/queueMatch with query 'regex' arg, which processes entire crawl queue on backend and returns a list of matches (more experimental)
- if crawl not yet started / redis not available, return empty queue
- only supported for k8s deployment at the moment
