Put into OWNERS files what has effectively been happening
for the past few months, we review and shepherd PR's
through other SIG reviewers before bringing to sig-arch
for a final /approve.
The goal is to eventually grow approvers when it's been
demonstrated that we have sufficient context.
This test creates a golden list of existing conformance tests. Efforts
to add or remove conformance tests will require you to rebuild the
golden list, and changes to the golden list will be reviewed by
sig-architecture.
