> AllocationTagsManager currently supports node and cluster-wide tag cardinality retrieval.
> If we want to support arbitrary node-groups/scopes for our placement constraints TagsManager
should be extended to provide such functionality.
> As a first step we need to support RACK scope cardinality retrieval (as defined in our
API).
> i.e. how many "spark" containers are currently running on "RACK-1"
