Document ">PASSWORD:Auth-Token" real-time message

Authentication tokens are security enhancement eliminating client
need to cache passwords, and are indispensable at two factor
authentication methods, such as HOTP or TOTP.

The ">PASSWORD:Auth-Token" message was not mentioned anywhere in
the OpenVPN Management Interface Notes. This patch adds a simple use
case example, while the more detailed feature description remains
explained in the OpenVPN manual.
