Dynamic Featured Server IPs

• Fetch IP from featured server domain instead of using hard-coded addresses. (Implementation by @CrafterPika )
  NOTE: If you have a setup with a BedrockConnect server instance hosted that is on a machine or router connection that is using the same DNS that directs the featured servers to your BedrockConnect instance, the new default functionality on this update will redirect back to BedrockConnect as it's dynamically grabbing the IP from the domain name from the host machine. If you have a setup like this, you will need to add the following to your run/startup arguments of BedrockConnect, so it continues using the hardcoded IPs: fetch_featured_ips=false
