Handle Websocket disconnect gracefully

[mattsse]

In the event the websocket crashes no more commands can be send or received so in that we case we should

• drop the Handler entirely short term
• add the option to try a reconnect, number of retries should be configureable.

For some reason I am seeing websocket crashes in my Github CI, with the log Error: chromiumoxide::handler: WS Connection error: Ws(Protocol(ResetWithoutClosingHandshake)). So it might help to get a reconnect.
