[FEATURE] Support web-access to ssh server with TRASA PAM installed.

Describe the feature:

If TRASA PAM is installed in ssh server, it expects keyboard-interactive authentication.
TRASA proxy should implement keyboard-interactive authentication for such case.
Currently we only support this when accessing from ssh clients.

Scope of feature:

• TRASA codebase
• dashboard
• server
• mobile app
• browser extension
• device agent
• website/docs
