YIP 10: Transitionary YFI Only Voting

I agree with this as a short term solution but I think have input from other defi products is important. yearn and YFI are built on top of these protocols and giving their members a voice in yearn makes space for cross-protocol collaboration will increase integrations and yields for YFI holders in the long run.

We should add more third party stake holders to governance process but cap their total below majority required to pass a vote so some YFI holders must always be in agreement.
