gfapi: add function to set client-pid
This api offers the ability to set the pid of a client to a particular value, identical to how gluster fuse clients provide the --client-pid option. This is an internal API to be used by gluster processes only. See https://lists.gluster.org/pipermail/gluster-devel/2019-March/055925.html for more details. Currently glfsheal is the only proposed consumer. updates: bz#1693155 Change-Id: I0620be2127d79d69cdd57cffb29bba44e6e5da1f Signed-off-by: Ravishankar N <ravishankar@redhat.com> (cherry picked from commit 08d502c3b05c6f7831bb4cc764bd458b405a99b1)
