Message Queue performance and consuming latency monitoring

Message Queue server plays an essential role in today's distributed system to reduce the length and latency of blocking RPC and eventually improve user experience. But in this async way, the measure for queue consuming traffic and latency becomes significant.

SkyWalking leverages native tracing agent and Extension Header Item of SkyWalking Cross Process Propagation Headers Protocol v3 to provide performance monitoring for the Message Queue systems.

In default, we provide Message Queue Consuming Count and Message Queue Avg Consuming Latency metrics for service and endpoint levels.

More metrics could be added through core.oal.
