ThreadMetricGroup

Stable id for the bucket (companyId, tierId, label id, etc.).

Display name resolved from value (e.g. the company, tenant, tier, label type, customer group, user or priority name). Null when there is nothing to resolve: the __OTHER__ bucket, an entity that no longer exists, or a dimension whose value is already the display string (MESSAGE_SOURCE, THREAD_FIELD, TENANT_FIELD).
