Current usage of Linux perf requires defining the COMPlus_PerfMapEnabled before starting the application.

There are scenarios were it would be ideal to be able to profile an application instance is performing poorly.

@brianrob Suggested adding a mechanism to trigger this. Perhaps through the diagnostics port.

Re-opening per offline conversation with @sdmaclea. This is still desired functionality.
