bq. Make StorageProxy non-blocking

For info, CASSANDRA-5239 is open for this (and I have 3 quarters of a patch written, which
I'm going to attach soonish).

> With MutationStatement.execute turned into a no-op, I only get about 33k insert_prepared
ops/s on my laptop.  That is: this is an upper bound for our performance if Cassandra were
infinitely fast, limited by netty handling the protocol + connections.
> This is up from about 13k/s with MS.execute running normally.
> ~40% overhead from netty seems awfully high to me, especially for insert_prepared where
the return value is tiny.  (I also used 4-byte column values to minimize that part as well.)
