[#CONTROLLER-1941] Controller does not quarantine on isolation/unisolation in cluster

1. geo-cluster - odl1 to odl6
2. set odl1-odl3 as voting, odl4-odl6 as non-voting
3. isolate odl6 using iptables
4. wait for 5 mins
5. unisolate using iptables -F
6. the odl1/2/3 and odl6 will go into a quarantine loop as below:

This is actually an issue in akka upstream - https://github.com/akka/akka/issues/24764.
But the solution for this is only present in the artery based akka.
Hence, till we move to artery we need to add this workaround to make this scenario work.
