Title	Align on a label to mark a Module CRD as having a reportable status

Context

The different tools for Kyma like the CLI, Dashboard and also metrics for telemetry like to give status about the kyma module status. For that, the tools need a way to identify the module CRs so that they can use the status.state and status.conditions for introspection.

Currently there is no easy way to figure out these resources, they are spread across different API groups.

The goal is to have a unified way to know which CRD is representing a kyma module in order to leverage the status for reporting in a generic way

Decision

Have a consistent labelling on CRD level which indicates that this CRD is a represents a module status. The label is called kyma-project.io/report-module-status: true

Consequences

The approach will allow the different tools to dynamically search for CRDs having the proposed label. Determined CRDs will follow the conventions of module status and should be considered.
