As a session tool user I want to query the current shell for active session(s)

[bjornrog]

I want to query session tool doing something like this:

$ get_session -q
Active profile: awsops
Expiration: 23:05:17

Or if the session is switched to a role:

$ get_session -q
Active profile: awsops
Expiration: 23:05:17
Role: bf-awsopslab-admin
Role expiration: 10:23:05

Today we only have the '-v' option, and that only returns true/false for the validity of the session and the '-l' option that will list stored sessions.
