Porch migration to Nephio

[johnbelamaric]

Tracking issue for the migration discussed here: #450

Migration

• Create new repository
• Migrate v0.0.35 server code to new repository
• Get builds working in new repository
• Get base CI working in new repository
• Get Porch e2e tests working new repository
• Migrate v0.0.35 CLI code to a new porchctl CLI tool (instead of kpt alpha)
• Get the e2e for the CLI working (Add CLI e2e tests porch#10)
• Get the CI working for the e2e tests (server and CLI, see Clean up build and CI porch#4 (comment) and Add CLI e2e tests porch#10 (comment) for relevant notes)
• Release porchctl artifacts for download/install #481
• Consider re-introducing the changes in Revise package revision caching strategy kptdev/kpt#4094, but with additional E2E tests and related fixes (it seems to have some concurrency problems). This is in Revise caching strategy porch#8
• Migrate the Porch documentation to Nephio docs

Clean Up

• Remove unused controllers
• Move fleet-sync GCP-specific controller to a separate repo, and consider re-instating other GCP-specific controllers if desired
• Remove the "Task List" concept from PackageRevision
• Remove the Function CRD, as we are not using it
• Remove the "Package" CRD, as it is not fully implemented
• Consider removing OCI support. We don't use it today, and it is not as well exercised as the Git support

For the Porch e2e tests, it does some of them now but not the ones that require a cluster. We need:

• Image build and push working for PRs for the nephio-project/porch repo
• The make ci-test-porch needs to create a Kind cluster, deploy the code (make deploy), then set E2E=1 and do the make test. Right now, it doesn't set E2E so those tests are skipped.

nephio-project/porch#4 (comment) and the subsequent comments.

@electrocucaracha can you help with the above?

Once this is done, we will want to update the docs to all use porchctl instead of kpt alpha. We will still use kpt for some things (like function execution, etc.).
