Information about a particular DSCP entry for a sap-egress policy.
Entries are created by user.
Entries are deleted by user.
There is no StorageType object, entries have a presumed
StorageType of nonVolatile.
in the event that one policy has multiple entries, and
the tSapEgressDSCP values are the same, only one queue
will be created (the queue for the lexicographically
first tSapEgressDSCP).
