[web] Move request handling logic into cubicweb application. (closes #2200684)
We improve http status handling in the process:
``application.publish`` have been renamed to ``application.handle`` to better
reflect it's roles.
The request object gain a status_out attribute to convey the HTTP status of the
response.
WSGI and etwist code have been updated.
Exception gain status attribute
