Cloning this as a doc bug so that we can track the documentation when the feature is implemented.

+++ This bug was initially created as a clone of Bug #1470105 +++

Description of problem:
In bz1176018 we added support for pacemaker authkey. The authkey is automatically created and distributed by pcs. However pcs always reads it from and writes it to /etc/pacemaker/authkey. If a custom location for the authkey is specified in /etc/sysconfig/pacemaker, pcs ignores it. This leads to missing authkey from pacemaker point of view.


Version-Release number of selected component (if applicable):
pcs-0.9.158-6.el7


How reproducible:
always, easily


Steps to Reproduce:
1. Change authkey path in /etc/sysconfig/pacemaker .
2. Setup a cluster, add remote or guest nodes.
3. Pacemaker authkey is stored at /etc/pacemaker/authkey instead of the location set in step 1, remote and guest nodes don't work.


Actual results:
Custom authkey location is ignored.


Expected results:
Custom authkey location is respected.


Additional info:
Backing up and restoring of cluster configuration needs to be fixed as well.
