Kyle Suarez 7bc7864fc0 SERVER-35043, SERVER-22949: move geoNear implementation into aggregation
This commit removes the geoNear command and moves its implementation
into the aggregation framework. Users should use the aggregate command
with a $geoNear stage.

The implementation rewrite additionally removes the limit in the
$geoNear aggregation stage. To limit the number of results, use a $limit
stage.
