Add pprof endpoints

[torywheelwright]

Update oplogtoredis to serve the standard net/http/pprof routes from its existing HTTP server. You can try it out by running go tool pprof http://<host and port for oplogtoredis>.

You may want to bump the version though in the *.nix file at the root, so that a new docker image gets built.
