Monitor events with WebSocket

This is a websocket api, it supports to watch start and stop event of container(s).

The entrypoint of the websocket api is wss://${REGION}.hyper.sh:443/events/ws. In addition, it's same as other apis.

As a reference, here is an example websocket client (written by golang)

The websocket connection will be closed from the server side if:

• Server restart for maintaining

• Connection opened for a long time (exceed 24 hours by default)

• Error occured.

So the client should handle the close and reconnect if needed.
