TODO: Finalize the track naming.
Metrics tracks MUST use the namespace and track name format defined in Section 3
of [MOQMETRICS]. The Track Namespace consists of the tuples:
(moq://metrics.moq.arpa/v1/),(resourceID) where resourceID is a unique identifier
for the publishing resource.
The Track Name identifies the granularity level for the metrics being published,
specified as a single tuple (<granularity-level>) where granularity-level is a
value from 0 (Emergency) to 7 (Debug). Higher priority levels (lower numbers)
indicate more critical metrics that should always be reported.
