Current Behavior

Metrics are returned in turn from each worker in the cluster and include data about one current worker.

Expected Behavior

It is necessary to transfer the registration of metrics to the cluster master and the workers inform the master about their metrics via IPC or AggregatorRegistry

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

enable prometheus metrics
moleculer-runner -i 2
check metrics

Context

研究方向: Investigate the current metrics implementation in the Moleculer framework, particularly how metrics are registered in cluster workers. The expected solution involves moving metric registration to the master process and using IPC or the prom client AggregatorRegistry to aggregate metrics from workers. Look at the existing prom client example at https://github.com/siimon/prom client/blob/master/example/cluster.js for reference. Also check the Moleculer source code for files related to metrics handling.
