[BIP-14] Funding Proposal for the Balancer Foundation

Thanks for this great proposal @Tristan345!

Together with the new Operating Framework for Balancer DAO this is a super important step for Balancer to become even more decentralized and resilient.

Having a foundation that allows entities that need to interact in the meat space (e.g. requiring contracts with another legal entity) will allow Balancer protocol to grow much further in a sustainable way.
