Add the ability to remotely reconnect

[jwoertink]

With #71 we now have a way to remotely disconnect. The Ruby version has a way to pass a reconnect message to tell the client to reconnect

https://github.com/rails/rails/blob/e9ea600c24bb44317cf6176c34020a7d0e1060f3/actioncable/lib/action_cable/remote_connections.rb#L56-L57C45

It seems that by default, the actioncable.js lib already handles a reconnect. So this would more be to say "don't reconnect".
