WebSocket/Server sent events implementation

[kasperkristensen]

We want to implement some notion of server transmitted data, as we want to be able to transmit to the client when a batch job is completed, and as an example notify that a file is now ready to be downloaded. Should expandable upon later, such as pushing a notification when a user is mentioned in a comment on an order, etc.

Part of this ticket is investigating how we should approach this, as WebSocket/SSE is not very "RESTy". One idea would be to subscribe to an event, and when detected push to the client "you should GET /admin/batch/<some_id>", to keep it slim and still make use of the existing RESTFUL API.

In general, it is better to do what you said which is

• Client action
• Server process
• Server send event to client to fetch specific resources

One point in favour of that is that the socket does not transmit any data (simple security, response consistency)
