Adds RequestPoolUtils which exposes user to pool resolution, authorization,
and relevant pool configurations by wrapping Yarn classes that provide that
functionality. (To support CDH4, those Yarn classes will come from
thirdparty/cdh4-extras.) RequestPoolUtils is created once by the backend and
the instance lives for the duration of the process.

The test works by submitting a number of queries (parameterized) with
some delay between submissions (parameterized) and the ability to
submit to one impalad or many. The queries are set with the WAIT debug
action so that we have more control over the state that the admission
controller uses to make decisions. Each query is submitted on a
separate thread. Depending on the test parameters a varying number of
queries will be admitted, queued, and rejected. Once queries are
admitted, the query execution blocks and we can cancel the query in
order to allow another queued query to be admitted. The test tracks
the state of the admission controller using metric counters on each
impalad.
