[ClusterLabs] Pacemaker 2.0.1-rc3 now available

[Ken Gaillot]

Source code for the third release candidate for Pacemaker version 2.0.1
is now available at:

https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-2.0.1-rc3

I forgot to mention a new feature in the original announcement! As of
2.0.1, Pacemaker's bundle feature now supports podman for container
management, in addition to docker and rkt. podman is a docker
alternative that doesn't require a daemon to run containers, among
other differences. To use podman bundles, you need a recent resource-
agents release that includes the podman agent.

rc3 fixes a couple of regressions found in rc1: 

* Most importantly, rc1 introduced a regression when cleaning,
refreshing, or removing a resource while an operation on the resource
was in progress. An assertion would be logged, the cluster would be
delayed from responding to new events for a minute or so, and the
operation would be treated as timed out (which might cause fencing).

* libstonithd API headers are compatible with C++ again


A few other bugs were also fixed:

* crm_resource --clear and --move would have problems if a previous
ban/move had used the --lifetime option.

* If the pacemaker-attrd writer leaves the cluster, the remaining
instances will now immediately start a new writer election, avoiding
the possibility of delaying or losing updates received when the old
writer was shutting down.

* pacemaker-attrd now detects alert configuration changes when the CIB
is replaced entirely (previously it only watched for CIB modifications)

Everyone is encouraged to download, compile and test the new release.
We do many regression tests and simulations, but we can't cover all
possible use cases, so your feedback is important and appreciated.
