Description of problem:
When upgrading oVirt a 3.6 cluster losses its Hot plug cpu functionality since the config setting for that key has a wrong value
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Have a 3.6 cluster in oVirt 3.6 with Hot plug CPU used
2.Upgrade oVirt to 4.2
3.Test Hot plug CPU on the 3.6 cluster
3.6 cluster losses its Hot plug CPU functionality
3.6 cluster should support plug CPU functionality
The reason for this regression was a missing value in the config file for 3.6 and then he value was taken from the java code which was correct
However, getting rid from config defaults in the java code and a wrong setting that was added to the config file broke the feature
