OK thanks. Why i was asking. Ceph has switched a lot of output to stderr
when switching to cuttlefish. So for example right now the RBDPLugin
does not show any progress on snapshot rollback.

Is it correct to fix it this way:
    run_command($cmd, errmsg => "rbd snapshot $volname to $snap' error",
errfunc => sub { print STDERR shift; });
