Async delegate used by the exporter to obtain an auth token using rich context.
Provides additional fields (e.g. TokenResolverContext.identity)
beyond what TokenResolver offers.
Must be fast and non-blocking (use internal caching elsewhere).
Return null/undefined to skip the export for that agent/tenant group.
