Add docs for Kafka Monitoring

[Calm-Rock]

Relevant links and details:

• https://signoz.io/blog/kafka-monitoring-opentelemetry/
• https://github.com/shivanshuraj1333/kafka-opentelemetry-instrumentation/tree/vm-setup

Overall all these sections would be there:

Local (Mac/Linux/Windows)
VM (AWS, Azure, Google Cloud)
K8s
  strimzi
Confluent
Amazon MSK

For the local one, the above readme is helpful; let's focus on getting that out first.
