Tunneling with YARP

How awesome would it be if we could use YARP as a reverse proxy over WebSockets?

I have one public facing ASPNETCORE server. Then I have multiple small blazor-server applications running on multiple machines in customers infrastructure (behind firewall etc). It would be great if I could setup YARP as a reverse proxy over websockets/signlar so I can reach the sites from public facing server.

ASPNETCORE Server (domain.com):
```c#
.AddYarpWebSocketServerEndpoint("/someSite1");
.AddYarpWebSocketServerEndpoint("/someSite2");
.AddYarpWebSocketServerEndpoint("/someSite3");
```
NETCOREAPP adding YARP on Client machine 1 proxy app:
```c#
.AddYarpWebSocketClient("https://domain.com/someSite1", "http://192.168.1.100:5000" );
.AddYarpWebSocketClient("https://domain.com/someSite2", "http://192.168.1.101:5000" );
```
NETCOREAPP adding YARP on Client machine 2 proxy app:
```c#
.AddYarpWebSocketClient("https://domain.com/someSite3", "http://192.168.1.100:5000" );
```

Browser (domain.com/someSite1)->Public server (WebSocket/SignalR-server-Hub) | Client(WebSocket/SignalR) -> 192.168.1.100 (blazor server app)
