YARN-7522 introduced AllocationTagManager component which is storing simple
node to application-container mappings.
YARN-7653 added support for node-group/rack to application-container mappings.
I would like to keep this JIRA in order to efficiently manage container tags
under all possible Container state transitions (EXPIRED, RELEASED, KILLED
e.t.c). Currently we support only container allocation and completion states
just as a proof of concept.
Does it make sense?

> Each allocation can have a set of allocation tags associated to it.
> For example, an allocation can be marked as hbase, hbase-master, spark, etc.
> These allocation-tags are active in the cluster only while that container is
> active (from the moment it gets allocated until the moment it finishes its
> execution).
> This JIRA is responsible for storing and updating in the
> {{PlacementConstraintManager}} the active allocation tags in the cluster.
