Description

We have two schedulers currently in the codebase. We are hardcoded to use the SimpleRpcScheduler only at the moment. I was playing with trying to improve scheduling and wanted to slot in the FifoRpcScheduler but no means. Here I add means. I also add logging of RpcScheduler config so users can see the effect of toggling configuration.
