Worker Coordinator Profiler Enhancement

[IanHoang]

Is your feature request related to a problem? Please describe

Worker Coordinator can make use of a profiler that profiles AsyncProfiler. In order to use the Async Profiler, you should run the test with --enable-worker-coordinator-profiling and the results should be outputted to ~/.benchmark/logs/profile.log.

Describe the solution you'd like

The worker coordinator profiler should have more descriptive results that can inform which profile relates to which client and should be able to have its profile.log sorted.
