We generate a kdump.conf internal to initramfs. We can start generating
that file to put fence_kdump options and fence_kdump nodes in that file
even for pacemaker.

So dracut-module-kdump.sh implementation will always expect that fence
kdump optoins and nodes are passsed in /etc/kdump.conf.

It is only kdumpctl implementation which will look for these options in
/etc/kdump.conf and if it is not there it will assume we are dealing
with pacemaker and use existing code of pcs to get to list of nodes.

For fedora we can change options method even for pcs and now make it
mandatory that fence kdump options need to be passed through
/etc/kdump.conf file.

We should talk to pacemaker folks and figure out how can we pass
nodes also using /etc/kdump.conf so that they also make use of this
new API instead of kdump doing special processing for pcs.
