This removes a bunch of queries for bugs that are now
fixed, marked invalid, or no longer hitting and so old
and obscure that they are probably not issues anymore but
if they do crop up again, we can create new queries.
Change-Id: I1ac6a02bb518e8a8c58b5992d936f95c14e5051f
By default we add 'voting:1' to all queries so they are filtered
from the graph.
There are cases where we want to track bugs for non-voting jobs
in the graph, so add an 'allow-nonvoting' key for special bugs
that we want to track while we're trying to stabilize a job.
Updates the docs, adds a test query and unit test for the query
loader, fixes a bad query that was setting voting:1 already, and
removes the TODO in the query for bug 1539271.
