Callback registration for handlers

[marmeladhero]

I want to have option to register handlers with KeyFilter attribute. so I can register it like this:

builder.RegisterMediatR(
            MediatRConfigurationBuilder.Create(assembly)
                .WithAllOpenGenericHandlerTypesRegistered()
                .WithOpenGenericHandlerTypeToRegisterCallback(x => x.WithAttributeFiltering())
                .WithRegistrationScope(RegistrationScope.Scoped)
                .Build());

I know it can be done better 😞

I know it can be done better disappointed

I think it is good, thanks for the addition. A few minor things + tests and we should be good to go :)

You currently have six commits. You need to squash them into one commit.
