Goal: Continue work on "Kubebuilder plugin Phase 2" - plugins as separate binaries that can be discovered by the Kubebuilder CLI binary via user specified plugin filepaths.

Why is this important: Open the door for future OperatorFramework plugin (e.g. scaffolds smaller building blocks from operator-lib), OpenShift plugin (e.g. scaffolding specific to the downstream needs), or plugins for other programming languages that can be out-of-tree.

Dependencies (internal and external):

• Kubebuilder accepts plugin proposal phase 2 and have it implemented and released.

Prioritized deliverables :

• Plugins as separate binaries that can be discovered by the Kubebuilder CLI binary via user specified plugin filepaths.
• Plugins that can be written in any language.

Estimate (XS, S, M, L, XL, XXL): XL
