Subject: [PATCH 107/124] 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.
Patch on upstream master: https://review.gluster.org/#/c/glusterfs/+/22368/
Change-Id: I0620be2127d79d69cdd57cffb29bba44e6e5da1f
