Brian Palmer dd574808c2 cassandra batching, and batch up the page view updates 
Add a batch method that uses cassandra's BEGIN BATCH/APPLY BATCH
functionality to cut down on the number of network round trips, and
possibly save a bit of CPU time on the cassandra servers.

Since execute returns a result set, it can't be batched, so we add another
method update for INSERT/UPDATE CQL statements that don't return a
value.

Closes CNVS-3526

test plan: No behavioral change. Do a regression test that page view
information is still send to cassandra properly. You can check the debug
logs to see that the CQL statements are all sent in one big BEGIN BATCH
statement.
