lock: Add fencing support
design reference: https://review.gluster.org/#/c/glusterfs-specs/+/21925/
This patch adds the lock preempt support.
Note: The current model stores lock enforcement information as separate
xattr on disk. There is another effort going in parallel to store this
in stat(x) of the file. This patch is self sufficient to add fencing
support. Based on the availability of the stat(x) support either I will
rebase this patch or we can modify the necessary bits post merging this
patch.
