Interactive usage about ssh2

[mscdex]

If you set tryKeyboard to true and no other authentication mechanism works out and the server supports keyboard-interactive authentication, then the server sends a series prompts for the client to answer. The answers to these prompts (stored in an array in the same order as the prompts) are then passed to the given callback (finish). If the server says the answers check out, then you're authenticated and 'ready' is emitted. Otherwise it can either flat out deny you or ask you to answer some more prompts.
