Programmatic Endpoint configuration not used in UseSwaggerForOcelotUI

[rklfss]

Describe the bug
If you configure Swagger Endpoints dynamically in ConfigureServices(IServiceCollection services), those are not used when calling UseSwaggerForOcelotUI and you are getting the error "SwaggerEndPoints configuration section is missing or empty".

services.Configure<List<SwaggerEndPointOptions>>(cfg =>
{
    cfg ??= new List<SwaggerEndPointOptions>();

    foreach (var (name, svc) in _appSettings.Services)
    {
        cfg.Add(new SwaggerEndPointOptions
        {
            Key = name,
            Config = {
                new SwaggerEndpointConfig
                {
                    Name = svc.Title,
                    Version = "v1",
                    Url = $"{svc.Url}/swagger/v1/swagger.json",
                },
            },
        });
    }
});

Expected behavior
The programmatic configuration is used.

Possible fix

Do not re-read the configuration section in UseSwaggerForOcelotUI and read from configured options instead.

public static IApplicationBuilder UseSwaggerForOcelotUI(
    this IApplicationBuilder app,
    // no need to use a configuration section here
    Action<SwaggerForOcelotUIOptions> setupAction)
{
    var options = app.ApplicationServices.GetService<IOptions<SwaggerForOcelotUIOptions>>().Value;
    setupAction?.Invoke(options);
    UseSwaggerForOcelot(app, options);

    app.UseSwaggerUI(c =>
    {
        InitUIOption(c, options);
        IEnumerable<SwaggerEndPointOptions> endPoints = app.ApplicationServices.GetService<IOptions<List<SwaggerEndPointOptions>>>().Value;
        AddSwaggerEndPoints(c, endPoints, options.DownstreamSwaggerEndPointBasePath);
    });

    return app;
}

This also works for file based configuration as the options are already configured in AddSwaggerForOcelot().
