Support for Component Islands

[rynowak]

Scope

You can add a component to a view or page, and it will become interactive once the browser opens a websocket connection. This is similar to pre-rendering except it doesn't require integrating with the client-side router.

You can have multiple of these on a page.

Additionally, you can pass state (through parameters) to the component and it will just work to preserve your state when it becomes interactive.

This is already possible once we have the strong reconnects. It is essentially prerendering.

@danroth - is there anything we're tracking by leaving this issue open? I thought we did this.

Closing this as we already have support for it on server-side blazor. We can file a new issue if we want to cover client-side too.
