Add support for variadic arguments on provider constructor

[mumia]

Example:

dependencies.graph.Define(
        &dependencies.RouteRegistry,
        inject.NewProvider(
            routes.NewRouteRegistry,
            &dependencies.AuthenticationRoutes,
            &dependencies.AccountRoutes,
            &dependencies.BankRoutes,
            &dependencies.BaseRoutes,
        ),
    )

Where routes.NewRouteRegistry is:

func NewRouteRegistry(routes ...Route) RouteRegistry

Sorry for the long silence. I know I don't have CI or unit tests for every feature, but can you add a test that covers this feature and show that it and the other tests still pass?

[mumia]

@karlkfi We are already using this in a production environment. :) I will write some tests so you can merge it. Thanks for the reply.

Tests are failing because one of your imports is importing your fork, not the real path

Thanks!

This change has broken for slice arguments.

        if inType.Kind() == reflect.Slice {
            inType = inType.Elem()
        }

If arg type is []uint , inType will be uint and fail AssignableTo and ConvertibleTo .
