Notes on setting up Eth2 clients for Medalla testnet (Prysm / Lighthouse / Teku / Nimbus / Lodestar)

PLEASE NOTE:

• Prysm, Lighthouse, and Teku are attesting and proposing correctly following this guide
• Nimbus currently has a glitch that it syncs the beacon chain well but can't post any attestations. An issue has been created: #1443
• Lodestar also has a glitch that the beacon client hangs up and won't sync the beacon chain
• This guide will be updated once these issues have been resolved
