> Ensure there are shutdown hooks in place for the various oak-run commands that properly
stop the repository and release the clusterId.
> Many command construct a repository, then perform some operation and then shut down the
repository again. Shutting down the repository will release the clusterId change the state
of the clusterNodes entry back to inactive. In some cases commands execute for a longer period
of time and a user might kill the process. When this happens, the clusterId is not released
and stays in the active state with a lease that eventually expires. The command implementations
should be improved to register a JVM shutdown hook that ensures the repository is shut down,
even when the process is killed.
