This PR adds EIP-3085, which introduces the wallet_addEthereumChain RPC method. It's basically EIP-2015, without requiring the network to be switched.
I think 2015 is a great idea, but wallets may desire an RPC method that only adds a chain, without requiring that the network is changed. For example, allowing dapps to request network changes is bound to cause UX issues, especially as we see dapps moving to different layer 2 chains.
