Story (Required)

As a Primaza Developer, I would like Primaza forwarding the Service Classes to Worker Clusters Service namespaces so that discovery can be performed.

Background (Required)

As defined in the Primaza architecture document, we need to forward Service Classes created into Primaza's namespaces to all the service namespaces of all matching Worker Clusters.
These Service Classes will be then used by the Service Agents during discovery.

See epic for arch document link.

Glossary

Out of scope

• Protocol field
• Serverless field

In Scope

• Push Service Classes to Worker Clusters
• Constraints

Approach(Required)

When a Service Class is pushed to Primaza's namespace, the operator retrieves the Cluster Environment whose EnvironmentTag satisfies the Service Class's Constraints field.
The Constraints logic is also needed by Registered Services, hence it is suggested to implement it outside the Reconciler.

For all matching Cluster Environments, we need to push the Service Class into all its Service Namespaces.
