[ClusterLabs] Minor regression in pacemaker 2.0.2

[Ken Gaillot]

Hi all,

A minor regression has been found in pacemaker 2.0.2:

"stonith_admin --list-targets" will not work with fence agents other
than fence_xvm. Apologies for not catching that before release. Anyone
compiling or packaging 2.0.2 from source is recommended to include the
commits from the following pull request:

  https://github.com/ClusterLabs/pacemaker/pull/1808

It includes the fix for that as well as other minor release follow-up
that doesn't affect end users.

I consider the regression minor because in the course of fixing it, I
found that stonith_admin --list-targets had a couple of pre-existing
issues making it not very useful. It could only be run successfully on
the node running the fence device (which I will fix separately), and
for most fence agents, which output targets as "name,alias", it would
run them together as "namealias" (which is fixed with this PR, as a
beneficial side effect).
