Remove queries for dead bugs

Bug 1232748 and bug 1235437 haven't been seen in two weeks, and the the
launchpad pages for them, have them closed. So remove the queries, since
it should list bugs we want to track.

Add doc on queries.yaml

Now that people are contributing patches to queries.yaml, we should have
some docs on what we expect. This is a first pass at that.

Add launchpad support to check_success

Make check_success query launchpad to provide more useful output.

The goal is to make the output of check_success more useful by adding
bug title, and affected projects etc.
