lvm tools should move away from doing remote command execution.
As you mentioned before, this is the equivalent of "ssh node lvchange".
ssh or some other tool outside lvm is the right way to run the remote
commands.

Also, lvm should not assume that it's using dlm/corosync, or that this
kind of remote option will be possible to support.
