To Reproduce

1. Deploy chart in namespace-1
2. Attempt to deploy helm chart in namespace-2

It errors with message:

Error: INSTALLATION FAILED: rendered manifests contain a resource that already exists. Unable to continue with install: ClusterRole "pod-monitoring-role" in namespace "" exists and cannot be imported into the current release: invalid ownership metadata;

Describe the bug

There are two issues as below:

1. We are currently creating "pod-monitoring-role" ClusterRole to be able to run helm chart test container with necessary access. However, we don't need to create the ClusterRole every time we deploy the chart.

Therefore, "pod-monitoring-role" ClusterRole needs to be deployed only once as shared resource. Ideally, we should also be able to remove after helm chart test is executed.

2. Besides the shared GatewayClass also exhibit the same issue and therefore needs to be installed as shared resource.

Describe the expected behavior

A user should be able to deploy the helm chart to multiple namespaces
