Problem Statement

Now we have created kong/kubernetes-configuration repository to store CRDs corresponding to Kong configuration. The repo is expected to be shared by KIC and KGO. We need to import source of CRDs from internal packages to packages in kong/kubernetes-configuration.

Proposed Solution

• Change import source of CRDs to packages in kong/kubernetes-configuration
• Change the scripts to download CRD manifests from kong/kubernetes-configuration
• Remove CRD packages and CRD manifests in the repo (Should we do this? Maybe there are dependencies elsewhere)

Additional information

No response

Acceptance Criteria

• KIC imports CRDs from kong/kubernetes-configuration repo
• KIC generate manifests from CRDs downloaded from kong/kubernetes-configuration repo
• Documents mentioning CRD download URLs changed to URLs in kong/kubernetes-configuration
