[feature request] AddAspNetCoreInstrumentation After Routing Filter

[Kharlap-Sergey]

Component

OpenTelemetry.Instrumentation.AspNetCore

Is your feature request related to a problem?

In AspNetCoreTraceInstrumentationOptions we have Filter configuration
but

Filter = context => {
  var endpoint = context.GetEndpoint(); //Endpoint is null here
  ...
};

What is the expected behavior?

Expected

AfterRoutingFilter = context => {
  var endpoint = context.GetEndpoint(); //Endpoint is !not null!
  ...
};

Why?
Working with Endpoint Metadata is a standard in the Asp community.
So we can achieve something same we have with AllowAnonymous

   // Decompiled with JetBrains decompiler
   public static TBuilder AllowAnonymous<TBuilder>(this TBuilder builder) where TBuilder : IEndpointConventionBuilder
    {
      ref TBuilder local = ref builder;
      if ((object) default (TBuilder) == null)
      {
        TBuilder builder1 = local;
        local = ref builder1;
      }
      local.Add((Action<EndpointBuilder>) (endpointBuilder => endpointBuilder.Metadata.Add((object) AuthorizationEndpointConventionBuilderExtensions._allowAnonymousMetadata)));
      return builder;
    }

Which alternative solutions or features have you considered?
