Remove aggregators (#690)
Primarily, this removes aggregators, which have been deprecated since
1.4 and have been replaced by combiners. This removal sets us up to
provide aggregators as a separate jar artifact, outside of the main
Accumulo build, if there is a continued demand for them. In future, all
such "user library" type add-ons to Accumulo could be provided as
separate, optional component jars.
Also cleanup other minor deprecated items.
Also create a delegating ConnectorImpl to allow removal of old deprecated
methods from new AccumuloClientImpl. This ConnectorImpl reuses the
implementation moved to AccumuloClientImpl via a delegate field, but
keeps the old ConnectorImpl methods that weren't carried over to the new
interface.
