> The 'auth_methods' option is used by the server side of the SSH code to
> tell a connecting SSH client about the authentication methods that are
> supported by the server. The code still extracts and handles the
> 'auth_methods' option from Opts in appropriate places, but the Opts
> checking code in ssh.erl didn't allow that option to be specified.
