cubicweb #773448 refactor session and 'no connection' handling [resolved]

we should refactor session to have proper session objects instead of using connections as a session holder.

This should allow a better handling of session without connection as this occurs until any authentication occurs, making forgetpwd usable on site without anonymous access (that's the end goal).
