Kubernetes pod does not finish when term signal is sent

[sgandon]

Hello,
We have deactivated the stopping of the sig term in this PR. And now the signal reaches the JVM and hazelcast performs a gracefull shutdown.
But the process does not end and the pod remains running until K8s timesout and kills the container.
That would be nice to have a proper end of container and will make the updates faster in K8s.
I did not find a way to fix this :(
