A new RPC perform_tests has been added. This request will help us avoid reading hotplug generated logs, and instead we can stop hotplug right before it begins generating IO, and resume it when the test scripts are ready. Additionally a new command line option has been added to the hotplug application "--wait-for-rpc", which indicates that hotplug should wait for perform_tests RPC before starting its IO.
