Registering one filter type for multiple controllers doesn't work in one statement

[smriti21]

The issue was also in WebpApi but it is resolved. The fix is needed in Mvc as well. The following line of code doesn't work -

        builder.Register(
                ctx => c.Resolve<IProperty>())
            .AsActionFilterFor<BaseController1>()
            .AsActionFilterFor<BaseController2>()
            .InstancePerRequest();

Error: System.ArgumentException: 'An item with the same key has already been added.'

Part of Stacktrace:

   at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
   at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
   at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value)
   at Autofac.Builder.RegistrationBuilder`3.WithMetadata(String key, Object value)
   at Autofac.Integration.Mvc.RegistrationExtensions.AsFilterFor[TFilter,TController](IRegistrationBuilder`3 registration, String metadataKey, Int32 order)

The Autofac WebAPI implementation allows for a list of predicates to determine if a given filter applies to an action. I think this could reasonably easily be adapted to the MVC side of things. I'm not sure how much time we have to allocate to it, but if folks want it, we'd accept a PR.
