[regrep-cooperating] Cooperating Registries Proposal: version 0.7

Team,

Attached is the latest version of the Cooperating Registries Proposal. I
would be remiss not to acknowledge the tremendous contributions made by
Nikola on this proposal.

At this point the proposal has enough breadth and depth to be reviewed
by the broader TC. However there is still much cleanup to be done and we
are continuing to improve it.
