cannot supply username + password for use with commercial vpn services

[hjwp]

commercial vpn services usually require the use of a username and password, on top of all the normal cert/key based auth.

.ovpn files do provide the option to read the username and password from a separate file, so it might be nice to allow users to upload that?

Thanks, we'll look into how to provide support for these configurations for future releases!
