ziti-tunnel: --resolver option is not parsed correctly unless scheme is specified

[scareything]

The --resolver option is passed directly to url.Parse, which doesn't do what you'd expect if you specify e.g. a plain filename "file.txt" or an IP address "127.0.0.10" without the scheme ("file://", "udp://")

I see what you mean about input validation. You mentioned the file:// scheme. Does that mean ziti tunnel --resolver file://hosts.txt is a valid resolver? I'll research it if you don't happen to know off hand. Thanks.
