* Update kubeflow-conformance-program-proposal.md

* Update to RFC based on feedback.

- Kubeflow distribution
  - Added statement about expanding the conformance scope in the future
  - Added information about conformance versioning and expiration
  - Added out-of-scope issues for conformance tests: product quality/supportability, distribution development/channel
- Kubeflow application
  - Added the requirement that Kubeflow Application must be Kubernetes Application through self-attestation on deployment mechanism.

* Update kubeflow-conformance-program-proposal.md

Major changes:
- KF Distribution Certification
  - Proposed to include test contributions for all WGs, with some guidelines
- KF Application Certification: 
  - Reworded the guiding principle to ".... verifies that the application under test integrates well with Kubeflow."
  - Removed the clause "existing KF components is automatically certified". Components in KF project participates in distribution certification, but not application certification.
  - Left in the "k8s application" requirement for discussion
