profiling: add config option for enabling profiling Previously you could only enable profiling via the --profile option. This is awkward when trying to debug a server side operation. Let's add a config option to enable profiling. In the future, this could be extended to allow profiling a certain percentage of operations (and potentially reporting that information to an external service).
