Feature Request: passwords over stdin

[phr34k]

Could you support setting the password over stdin, so for example "somepassword" | sudo -u somebody whoami /priv could work. Presently the only option is to read from the console which gives an exception, which doesn't work in non-interactive sessions.

 Error: System.InvalidOperationException: Cannot read keys when either application does not have a console or when console input has been redirected. Try Console.Read.
