We currently only have timeouts for updates but we'll need to add them for
searches because bad nodes can take out the whole clusters if they sit on the
request, say, because they have bad heap settings.

We'll need to set the shard timeout as well so Elasticsearch can timeout those
requests.  It is much better for Elasticsearch to timeout the requests because
we'll get partial data and, if we timeout and just hit it again, then we can
fill its request queues.
