Hello
What is the purpose of lines 261 and 262? Is it to mount all docker containers and the host' filesystem so OTEL Collector can monitor the host it runs on?
Is it mandatory, or can I comment these lines?
<https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/docker-compose-minimal.yaml#L261>

Also, why is there a zookeeper-2 and zookeeper-3, same for clickhouse, in deploy/docker/clickhouse-setup/docker-compose-minimal.yaml ?

required for reading docker container logs

So that if someone wants to setup a three-sharded setup they can follow the example. They are commented out.
