Cluster Distributed lock service integration with OOM.
Disabled by default. In order to enable cluster replicaCount
should be higher than 2 and useScriptCompileCache is set to false.
We need to disable script compile cache otherwise there is
issue with updating CBA when running multiple replicas of
blueprint processor.
