Add support to track web sockets

[tahirmt]

It might not be possible to do automatic tracking but it would be nice to provide an interface for manual logging.

Here is what should be supported

• websocket connect. With possibly a request object
• Message sent
• Message received
• Websocket disconnect.

All of this can be tracked within one single line item with a list of back and forth messages. Alternatively each entry could be its own line item.

This feature is in the backlog. It should support both URLSessionWebSocketTask and other technologies, e.g. Network framework.

All of this can be tracked within one single line item with a list of back and forth messages. Alternatively each entry could be its own line item.

It'll be great to give users control over how it's tracked and/or displayed.
