231b7df6cc lvmlockd: improve VG removal for lock_type dlm
This makes lvmlockd removal steps for dlm VGs closely match
sanlock VGs.  Because dlm lockspaces are not required to be
stopped on all hosts before vgremove, there is an extra bit
for dlm lockspaces, where a flag is set in the VG lock lvb
indicating that the VG was removed.  If other hosts happen
to use the VG lock they will see this flag and stop their
lockspace.

fd1782b5fc lvmlockd: handle loss of sanlock lease storage
This adds the infrastructure, code paths, error reporting,
etc. to handle storage errors, or storage loss, under the
sanlock leases in a VG that is being used.  The loss of
storage means sanlock cannot renew its leases, which means
that the host needs to stop using the shared VG before its
leases expire.

This still requires manually shutting down a VG that has
lost lease storage, e.g. unmounting file systems,
deactivating LVs in the VG.  The next step is to
automatically use a command like blkdeactivate to do that.
