Hi, I have a couple commits to replace this one, which make it
configurable.  There are a couple small things left to look at.
See this branch:

https://sourceware.org/git/?p=lvm2.git;a=shortlog;h=refs/heads/dev-dct-lvmlockctl-kill-1

I've been testing this by just setting lvm.conf
	lvmlockctl_kill_command="vgchange -an"
and running lvmlockctl --kill <vgname>

We'll likely leave lvmlockctl_kill_command empty (disabled) by default for
now, with a suggestion to consider the blkdeactivate command.
