> YARN _getAllApplications()_ call with no param or with application types _getApplications(Set<String>
applicationTypes)_ are very costly in a cluster with hundreds or thousands of Slider apps
running.
> YARN now has the API to filter by application tags - YARN-4491. We should be able to
use this to avoid these expensive calls.
