Investigate how KIC could run without cluster role

[randmonkey]

Is there an existing issue for this?

• I have searched the existing issues

Does this enhancement require public documentation?

• I have added an Acceptance Criteria item for adding and/or adjusting public documentation (if applicable)

Problem Statement

From FTI-6416. Customer want to use KIC to manage only resources in one namespace and do not want clusterroles to be created for KIC.
Currently KIC need to reconcile several kinds of cluster scoped resources:

• IngressClass
• GatewayClass
• KongClusterPlugin
• KongVault
• KongLicense
  We need to know if KIC can run without reconciling these cluster wide resources so KIC can run without cluster riles, and what functions are affected if KIC is running in such situtaion.

Proposed Solution

• Check whether KIC can run without reconciling any cluster scoped resources
• Summarize affects on functions if KIC run without cluster roles

Additional information

No response

Acceptance Criteria

• Know how KIC can run without cluster role
• Have a document about what functions are affected if KIC run without cluster role
