Create a custom banner telnet honeypot

[lorg]

• Create a telnet service that can easily be configured to show any banner
• Should have a few builtin banners, at least one of them should be the cisco telnet banner (e.g. https://www.shodan.io/search?query=user+access+verification )

This is different than the existing banner service because this will be a full telnet honeypot (e.g. accepting telnet options, login, etc.)

The parameters should be:

• User/login for authentication - the users that will be accepted for authentication
• Banner - the banner that will be sent upon connection
