creationPolicy type does not support Tokens

Trying to convert the following to CDK-flavoured L2 constructs:

    CreationPolicy:
      ResourceSignal:
        Timeout: !Ref InstanceCreationTimeout
        Count: !Ref MinSize

However, the CDK types do not seem to support using anything other than a number. The following fails typescript compilation:

    autoscaler.options.creationPolicy = {
      resourceSignal: {
        timeout: new cdk.Token(instanceCreationTimeout.ref),
        count: new cdk.Token(minSize.ref)
      }
    };

The resourceSignal type only accepts number and undefined for count, meaning I can’t “cheat” and use a stringified nor a raw token.

Note that this is using CDK in its context as a “way to write cloudformation templates” rather than the entire app, so parameters / outputs / conditionals are being used.

@mipearson See #1455 - that’s probably a better way to support this. The reason we are trying to avoid union types in the APIs is because they can hardly be translated well to other programming languages.

I want to point out here that what I was trying to do was based on a lack of understanding of how CDK works, as this issues is referenced as a use case from another.

These values are no longer references in my stack: they’re available at compile / synth time.
