This commit is part of the websocket integration in Odoo.
It focuses on adapting the bus to support websockets:
- last notification id is now kept on the server
- channel list is built by overriding the `_build_bus_channel_list`
method of the `ir_websocket` model instead of overriding the `_poll`
method of the bus controller.
- The bus presence was updated during polls, since there is no more poll,
bus presence update will be the responsability of the client.
- The `/websocket/peek_notifications`, `/websocket/update_bus_presence`
routes will be available so that odoo sh can access notifications/update presence
from http requests.
- /longpolling routes are now prefixed with /bus thus won't be redirected to the
gevent worker anymore except for `/longpolling/health` which is the
health check route of the gevent server.
Since websocket now handle incoming messages, a way to manage authentication
have been introduced :
- The session is retrieved from the HTTP handshake.
- When a websocket message comes/leaves the session is retrieved
on the file system so that we're sure it still exists and that
it is up to date.
- The session is checked
- If no session is found on the file system or `check_session`
fails, the websocket connection is closed with the `SESSION_EXPIRED`
close code (which is a custom close code: 4001).
- Note that websocket connections are closed every `KEEP_ALIVE_TIMEOUT`
seconds to ensure no websocket connection will stay open if the user
clears its cookies.
- Note that a wsrequest object is available when processing incoming
messages. It is similar to the http request and contains various
useful informations (session, env, ...).
