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.)
