Unexpected behavior occurs after OOM exceptions

Issue: JDG-3991

Description: If out of memory exceptions cause Data Grid Server to terminate on OpenShift, unexpected behavior can occur. In some cases nodes cannot restart and the org.infinispan.LOCKS enters degraded mode. The following exception is written to the pod log file: 

FATAL (main) [org.infinispan.SERVER] ISPN080028: Red Hat Data Grid Server failed to start java.util.concurrent.ExecutionException: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Initial state transfer timed out for cache org.infinispan.LOCKS on <pod-name-id>
