> Create event cache for queue and application events

> Key: YUNIKORN-117
> URL: https://issues.apache.org/jira/browse/YUNIKORN-117
> Project: Apache YuniKorn
> Issue Type: Sub-task
> Components: core - cache, core - scheduler
> Reporter: Adam Antal

> Create a simple preliminary implementation of the event cache of YUNIKORN-42.
> We have the following limited scope for this task:
> - implement it as a separate process from the scheduler (similar to
> {{PartitionManager}})
> - only deal with queues and applications (the pods and nodes can be added
> later)
> - only store the apps last visited time from the scheduler
> - clean up those objects that haven't been visited in the last 24h
> Other cache implementations can be also considered.
> As a starting point, channels are a safe choice to have async communication
> with the scheduler without expecting bigger performance loss.
