[bug 744997] Fix /service/monitor

Reworks memcache checking to parse the "new" cache setting format described
at https://docs.djangoproject.com/en/dev/topics/cache/ .

The only thing I didn't do was add handling for the unix: variant of
location. I don't think we use that and I'm not sure how to test it anyhow.
Handle ; separated locations.

[bug 719403] Remove eye symbol and combine watch/unwatch into one toggle

the same.

[bug 757666] Add --checkindex to esstatus

--checkindex will cause esstatus to go through everything in the db
and make sure it's in the index. It's not verifying that the data in the
index matches what's in the db--only that at least something is in the
index.
[bug 757666] Add a prefix to _id

This changes _id (the document id) to include the model name. That way if
two documents have the same db id, the last-to-be-indexed document doesn't
stomp on the prior ones.

Note that _id is the elasticsearch document id and shouldn't be confused
with document['id'] which is just a field in the document named id which
matches the id in the database.

Also note that at the moment, elasticutils assumes that _id is an int, so
doing anything that causes it to do ObjectResults kicks up an error. That
needs to get fixed, but can be pushed off until I figure out how to do it
in a way that's not fundamental to how elasticutils thinks about the world.

Skip the test that fails arbitrarily

This test fails like once a month. But that's annoying and it's in the queue
of things to rewrite. So for now, we'll skip it.
