Expose endpoint for dotnet counters

Exposing an endpoint for dotnet-counters is easy. Follow these steps:

1. Add NuGet package:

   • OpenDotNetDiagnostics.Counters.WebEndpoints.

2. Update the code in Program.cs:

   var builder = WebApplication.CreateBuilder(args);
   ...
   // Add dotnet-counters services
   builder.Services.AddDotNetCounters();
   
   var app = builder.Build();
   ...
   // Expose an endpoint at `/dotnet-counters`
   app.MapDotNetCounters("/dotnet-counters");
   app.Run();

3. Hit the endpoint:

   • Run your app, assuming its hosted at http://localhost:5555.
   • Invoke: PUT http://localhost:5555/dotnet-counters, with body:

     {
         "isEnabled": true,
         "invokingSecret": "1111"
     }

Notes: There will be no output, yet, since there are no sinks.

Please refer to [ues dotnet-counters local file sink] or [use dotnet-counters azure blob sink] for how to configure the outputs.
