Small update for cluster support
- Improved visualization of cluster nodes that we lost contact to
- New kernel parameters to reduce hard-coded values and to make purpose more explicit
* new parameter ClusterHeartbeatInterval (default 20s),
was hardcoded before to the new default value

* renamed EnableLoggingP -> ClusterEnableLoggingP
- Bumped version numbers:
