IMPALA-4889: Use client sidecars for Thrift RPCs

This patch changes the way Thrift structures are serialized with
KRPC. Instead of serializing them to a byte stream, and then writing
that stream to a Protobuf object which is serialized again en route to
the wire, the Thrift objects are serialized to byte streams which are
then directly written to the wire as a 'sidecar'. This saves a copy and
serialization step both on the sender and receiver sides of the RPC.
