rpc-bench: add async benchmark, make more configurable
This changes rpc-bench to have an 'async' mode which uses a smaller
number of client threads which have multiple outstanding calls.
It also now reports the number of context switches per call as well
as the parameters used to run the test.
Baseline results on a 24 core 2.5Ghz (48 logical cores) system:
./bin/rpc-bench -server_reactors 24 -async_call_concurrency 100 -worker_threads
40 -client_threads 24 -run_seconds 3
Mode: Sync
Client threads: 24
Worker threads: 40
