Thomas Schoebel-Theuer 92d9778dd7 fix race on primary switchover 
solution: wait until all in /mars/resouce-*/ has stabilized

This more a workaround than a solution and should be fixed
in MARS FULL.

Thomas Schoebel-Theuer 81bfb9471a fix network race on primary/secondary switch 
The race could lead to unnecessary split brain.
Now we wait until everything in the resource directory became stable
for at least 60 seconds. This may be somewhat too conservative
when having k>2 participants on the same resource.
