[cwuser] make CWUser callable, returning self for dbapi compatibility

In the dbapi, Connection and Session have a ``user`` method to
generated a user for a request In the repo api, Connection and Session
have a user attribute inherited from SessionRequestBase prototype. This
ugly hack allows to not break user of the user method.

To ease transition from dbapi to repoapi we need the ClientConnection to be as
compatible as possible with the dbapi. Adding this method goes in this
direction.

It'll get deprecated in the deprecation wave that will conclude the repoapi
refactoring.
