           Summary: gfapi: API needed to set lk_owner

+++ This bug was initially created as a clone of Bug #1499641 +++

Description of problem:

Glusterfs server differentiates locks based on both client-id and lock owner.
There is no provision to set lk_owner as of now via gfapi. Hence a new API is
needed to set the same. Since the lk_owner is associated with a particular glfd
(until we get mandatory lk support), the API definition looks like below -

"glfd_set_lk_owner()"

    gfapi: set lkowner in glfd

    We need a provision to be able to set lkowner (which is
    used to distinguish locks maintained by server) in gfapi.
    Since the same lk_owner need to be used to be able to
    flush the lock while closing the fd, store the lkowner
    in the glfd structure itself.

    A new API has been added to be able to set lkowner in glfd.
