Add a RegisterLazy methods that accept a Func<...> instead of IRegistrationMutator

[cyrildurand]

I have case where I need to use the WithParameter method on the original type :

ie :

builder.RegisterLazy<IEventSender, CompositeEventSender>()
            .WithParameter((pi, c) => pi.ParameterType == typeof(IEnumerable<IEventSender>), (pi, c) => c.ResolveNamed<IEnumerable<IEventSender>>("inner"));

I understand why I can't use this code and I need to implement a IRegistrationMutator

builder.RegisterLazy<IEventSender, CompositeEventSender>(myMutator); 

instead of having to implement a whole classe that will be used only once would that be possible to add a new parameter to the RegisterLazy

builder.RegisterLazy<IEventSender, CompositeEventSender>(b => b.WithParameter(...)) 

Let me know if you want me to make a pull request
