Implement the remaining runtime profiling subcommands for `runsc profile`: - `goroutine`: Dumps the current stack traces of all running goroutines in Sentry. - `block`: Collects a goroutine blocking contention profile. - `mutex`: Collects a mutex contention profile. - `trace`: Collects an execution trace.
