[ClusterLabs] Pacemaker with Zookeeper??

 From my point of view (and yes, I'm biased), biggest problem of 
Zookeper is need to have quorum 
(https://zookeeper.apache.org/doc/trunk/zookeeperAdmin.html#sc_designing). 
Direct consequence is inability to tolerate one node failure in 2 node 
cluster -> no 2 node clusters (and such deployment is extremely 
popular). Also Corosync can operate completely without quorum.
