In order to know whether or not the websocket session is up to date,
the session is saved when opening a websocket connection. Then, for
each incoming/outgoing message, we check if the session still exists
on the file system. When it does not exist anymore, the websocket
connection is refreshed. This ensures the session is always up to date.
Odoo sh proxies the websocket connection and needs a way to tell
when a websocket session is expired. This commit adds the same
check that is done for each incoming websocket message in the
websocket peek route in order to raise a `SessionExpiredException`
when the session is outdated.
This will allow odoo sh to catch this error and to refresh their
websocket connection accordingly.
