   Don't OAL support labeled AVG metrics ? 
   
   I'm  analyzing MQ metrics , I think it's better to provide transmission 
latency metrics labeled by `queue` or `topic` , as  following :
   ```
   mq_transmission_latency = 
from(MessageQueueAccess.transmissionLatency).filter(operation == 
MessageQueueOperation.Consume).avgLabeled(MessageQueueAccess.queue);
   ```
   But  `AvgLabeledFunction` is in meter package , and  annotated by 
`@MeterFunction`. 
   
   `MetricsHolder` only initialize Class annotated by `@MetricsFunction`
   
https://github.com/apache/skywalking/blob/5abe6ceb1ff0938be917f8b440c5eb3590cf31db/oap-server/oal-rt/src/main/java/org/apache/skywalking/oal/rt/parser/MetricsHolder.java#L41-L45
   
   Could I implement labeled AVG  metrics in OAL if It's not supported ?
   If the answer of the above question  is Yes  , Should I add a new Labeled 
AVG metrics class to `metrics ` package , instead of using `AvgLabeledFunction` 
class  in `meter` package  ?
