Export of subscriber accounting, dynamic interface,and interface-set queue statistics through JTI

You can export statistics associated with dynamic subscriber interface stacking through remote procedure calls (gRPC). Accurate statistics (actual transit statistics) sensor for the subscriber interface includes IP (total) and IPv6 ingress and egress packets and bytes. Queue statistics for dynamic interface and interface sets include include counts of transmitted and dropped packets and bytes. The queue statistics sensors are maintained per contributing slot (as in the case with AE). Separate metadata sensors convey more contextual information about the dynamic interface and interface sets are available. The metadata sensors are also eligible for ON_CHANGE streaming. To enable subscriber and queue statistics for telemetry, include the subscriber-statistics and queue-statistics statements at the [edit dynamic-profiles profile-name telemetry] hierarchy level.
