IMPALA-1169: Admission control info on the queries debug webpage
This patch adds a new event, 'Queued', to the query event log to
indicate when a query is queued by the admission controller. This
means that queries on the '/queries' page that are currently
queued will display this as their 'Last Event', making it possible
to see which queries are current queued.
It also adds a column to show the resource pool associated with
the queries, and it updates the wording of the first event that
gets marked for each query from 'Start execution' to 'Query
submitted', since this is before planning and admission control
and therefore execution hasn't actually startd yet.
