TUN-7021: Fix proxy-dns not starting when cloudflared tunnel is run 

This PR starts a separate server for proxy-dns if the configuration is
available. This fixes a problem on cloudflared not starting in proxy-dns
mode if the url flag (which isn't necessary for proxy-dns) is not
provided. Note: This is still being supported for legacy reasons and
since proxy-dns is not a tunnel and should not be part of the
cloudflared tunnel group of commands.
