opentelemetry-operator.v0.104.0

Description of the problem:
When a OpenTelemetry Collector instance with enableMetrics is created in a non openshift- prefixed namespace, the namespace of the instance doesn't show in the OpenTelemetry Collector dashboard Namespace drop-drown. 

Steps to reproduce the issue:
1. Deploy and install the OpenTelemetry operator built off the latest upstream branch.

2. Create a OTEL collector instance with enableMetrics:true in the collector config in a non openshift prefixed namespace. 

% oc project chainsaw-otlp-metrics 
Already on project "chainsaw-otlp-metrics" on server "https://api.ikanse-221.qe.devcluster.openshift.com:6443".

% oc get pods

3. Check the namespace drop-down in the OpenTelemetry collector dashboard. The OTEL collector instance namespace is not shown. However the instance can be seen and selected in the collector instance drop-down.
