Ability to monitor circuit activity

[SteveSandersonMS]

Ability to monitor circuit activity so that circuits can then be terminated as appropriate. Provide callbacks when an event, JS interop call, or other activity happens on the circuit.

The ability to terminate circuits from client/server is tracked separately by https://github.com/dotnet/aspnetcore/issues/17866.

Is it possible to access Blazor's signalr hub/hubcontext to disconnect clients and to override the OnConnectedAsync and OnDisconnectedAsync events as a workaround? How about making the HttpContext used to establish the underlying signalr connection available when a circuit is opened/up?
