Hoodi testnet

This write up will help you understand the initial distribution of validators among the new hoodi testnet. This testnet will launch in case we decide to do plan A of this writeup. Given: Ethpandaops controls 33% of the validators. The remaining 67% should be split among:11 client teams (each with approx. the same share). 5 staking operators (each with a slightly smaller share). Total staked ETH: At least 20M ETH. Each validator balance: Between 32 ETH and 2048 ETH.
