Automate the generation of the Conformance Document

[Srini Brahmaroutu]

As part of the release process we should generate the conformance document and check it into kubernetes documents

• the release build should trigger a prow plugin to create conformance document
• the generated conformance document should be attached to the release (like a release note)
• the generated document should also be checked under cncf/k8s-conformance/docs (optional)

@brahmaroutu While trying to create the conformance docs for 1.10, 1.12, 1.13, 1.14 and 1.15 I ran into a few problems.

• The template for the markdown document is in master which caused issues when checking out other kubernetes versions before creating the docs for that version.

• To generate the document for 1.10 required removing the regex check for Flaky
