[Epic]: Implement Rate Limiting Middleware in aspnetcore

[rafikiassumani-msft]

• Review current implementation in aspnetlabs
• Ensure the middleware will work for YARP
• Release the middleware to get feedback

API Proposal:

namespace Microsoft.AspNetCore.RateLimiting
{
    public sealed class RateLimitingOptions
    {
        public PartitionedRateLimiter<HttpContext> Limiter { get; set; }
        public Func<HttpContext, RateLimitLease, Task> OnRejected { get; set; }
        public HttpStatusCode RejectionStatusCode { get; set; }
    }

    public static class RateLimitingExtensions
    {
        public static IApplicationBuilder UseRateLimiting(this IApplicationBuilder app)
    }

    public static class RateLimitingServicesExtensions
    {
        public static IServiceCollection ConfigureRateLimiting(this IServiceCollection services, Action<RateLimitingOptions> configureOptions)
    }
}

Thanks for contacting us.

We're moving this issue to the .NET 7 Planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s).
If we later determine, that the issue has no community involvement, or it's very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues.

Thank you for submitting this for API review. This will be reviewed by @dotnet/aspnet-api-review at the next meeting of the ASP.NET Core API Review group. Please ensure you take a look at the API review process documentation and ensure that:

• The PR contains changes to the reference-assembly that describe the API change. Or, you have included a snippet of reference-assembly-style code that illustrates the API change.
• The PR describes the impact to users, both positive (useful new APIs) and negative (breaking changes).
• Someone is assigned to "champion" this change in the meeting, and they understand the impact and design of the change.

API Review:

• In the future Limiter will be aggregated with default behavior
• Remove IServiceCollection extension method for now
• RateLimiting -> RateLimiter in method and class names

namespace Microsoft.AspNetCore.RateLimiting
{
    public sealed class RateLimiterOptions
    {
        public PartitionedRateLimiter<HttpContext> Limiter { get; set; }
        public Func<HttpContext, RateLimitLease, Task> OnRejected { get; set; }
        public int DefaultRejectionStatusCode { get; set; }
    }

    public static class RateLimitingApplicationBuilderExtensions
    {
        public static IApplicationBuilder UseRateLimiter(this IApplicationBuilder app);
        public static IApplicationBuilder UseRateLimiter(this IApplicationBuilder app, RateLimitingOptions options);
    }
}
