Grpc client with host and port information

hi,

This question has already been asked [here](https://github.com/grpc/grpc/issues/34073)

Does the Grpc client have additional methods or properties to get the server name, port number of the server. Like, I can see one method `WithHost` in `namespace Grpc.Core` . Also, this is in C# and might be needed in other languages too.

I know the `GrpcChannel` type has it like `channel.Target` in the below snippet to get that information.

```
var channel = GrpcChannel.ForAddress("http://localhost:1357");

var appCli = new App.AppClient(channel);
```

I need something like `appCli.Target` or similar to get that info.

PS - During debugging I could get that info from `(Grpc.Net.Client.Internal.HttpClientCallInvoker) appCli.Configuration.undecoratedCallInvoker`, however I could not use it in code as `HttpClientCallInvoker` is `internal` or `Configuration` method was not accessible.

The reason why I am asking is, say if I connect to n servers, then I need to maintain a key value for each client connection. With this feature or enhancement, I might not need to.

Apologies if this question is already answered!
