Session recording

[blaubaer]

Is your feature request related to a problem?

If something security relevant happens within the session, there is no audit log, rather than the log files who logged in, etc. but I cannot see what the user actually have been done.

In high security environment, this can be very crucial.

Describe the solution you'd like.

Bifröst should have the possibility to record everything in asciinema compatible format. This will enable an exact playback, later.
