Feature Request: Integrate ObjectPool into Dependency Injection

[grochoge]

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

Right now if a service/etc wants to use an object from a Microsoft.Extensions.ObjectPool, it needs to know it's getting a pooled object.

There's also no way to customize service resolution and dispose behavior of the dependency injection machinery.

Describe the solution you'd like

Provide a way to automatically resolve a service from an object pool and return at the end of a scope (checking IResettable.TryReset if applicable). Perhaps something like a .AddPooled<IExampleService, ExampleService>( maxCount: 10 ) as an alternative to .AddScoped<IExampleService,ExampleService>().

Or at least provide customization hooks in the DI machinery so we can implement this ourselves.

I suspect DI pooling has come up before. @halter73?
