As a Solutions Architect
I want to have consumer lag for kafka consumers available out of the box
so that I can correctly monitor streaming applications without having to setup an external prometheus. In addition Consumer lag is the key metric to monitor for end to end health of streaming apps(ie to ensure they are keeping up with demand), you cannot put a streaming app into production with out correct monitoring and alerting on this metric.

Background
1. there is a consumer lag on the default metrics dashboard but it does not work.
2. I contact support and found that consumer lag is an early access feature that they enabled for me, but in order to get it into grafana it requires setting up an external prometheus(we cant do it all natively in Aiven)
3. Here is support ticket for Reference: #89595
