Start SSH Keyboard-Interactive Authentication

Demonstrates the Chilkat Ssh.StartKeyboardAuth method, which begins keyboard-interactive authentication. The only argument is the login name. It returns XML describing the server's prompts and whether each response should be echoed. Answer the prompts with ContinueKeyboardAuth.

Background: Keyboard-interactive is the flexible, prompt-driven SSH method — the server sends one or more questions (a password, a one-time code, a security question) and the client answers each. It is how SSH supports two-factor and other challenge-response schemes. The returned XML tells you exactly what to ask the user and whether to mask their input.
