Unable to run opentelemetry-collector in namespaced mode

[alita1991]

Describe the bug

Provide a way to run the opentelemetry-collector in namespaced mode (without the need for a cluster-role)

Steps to reproduce

Deploy opentelemetry-collector with a role and add a receiver that will access the K8S API (ex: prometheus)

What did you expect to see?

No RBAC errors should be reported

What did you see instead?

RBAC errors are printed to console, where resources like Pods, ReplicaSets are being listed at the cluster level, instead of namespace.

Additional context

I want to be able to run otel-operator + collectors in a K8S environment, where I only have access to a namespace.

[codeboten]

this appears to be an issue w/ the operator, maybe one of the @open-telemetry/operator-maintainers there can move transfer the issue

[jaronoff97]

@codeboten we already have an open issue there with a similar description. I think we can close this in favor of that one. sorry... this issue

Thanks @jaronoff97! Closing as a duplicate of open-telemetry/opentelemetry-operator#3042, @alita1991 please let us know if that issue doesn't capture your concerns.
