the mon, osd and mds register a "heap" asok command that forwards to ceph_heap_profiler_handle_command, but the mgr never did, so `ceph daemon mgr.<id> heap stats` returns "no valid command found". that leaves no way to tcmalloc-profile a leaking mgr through its admin socket, which is what chasing mgr memory growth needs. register the same command on MgrStandby's admin socket. its hook lives for the whole process, so it works on both the standby and the active mgr. heap output goes to the bufferlist, as on the other daemons, while status keeps using the formatter.
