Periodically clean-up cluster tasks from offline nodes

Problem Definition

Assume some node in JIRA Datacenter is executing long-running task with has cluster-wide status. If at some point progress abnormally stops before the job is complete, then job will be stuck for the whole cluster.
The stuck job is stored in an in-memory cache and is replicated to other nodes when they start. All nodes must be shut down at the same time in order for this job to be removed from cache.

Suggested Solution

Implement the job which periodically cleanup tasks from the nodes that are offline for a long time.

Implemented Solution
