Ceph

reason is simple: ceph_heap_profiler_handle_command() in perfglue/heap_profiler.cc expects two args in the vector, the second being the command (the first, I'm assuming, would have been 'heap' in previous versions).

solution: check whether we're using this in other places besides the monitor in the same fashion as it was before, and if so we should either change them to pass only the arguments to the profiler (without the 'heap' as first argument) as the monitor does, and adjust the handler function to not assume 2 arguments; or add 'heap' as the first argument in the vector on the monitor.

Not having this working properly makes the whole profiler unusable. And that's not great.
