Code Issues Proposed changes

Increase corosync token timeout 

This might prevent dropping members from corosync cluster on high load
environments. Symptoms of this problem happening can sometimes be found
in corosync log:

dub 05 17:23:45 overcloud-controller-0 corosync[14152]: [MAIN ] Corosync
main process was not scheduled for 3691.8391 ms (threshold is 1320.0000
ms). Consider token timeout increase.

The default in the Puppet manifest is 1 second, which matches the
corosync default, and we override it with hiera to 10 seconds.
