Provide a way to create a copy of a Key with an annotation

[kashike]

This allows you to easily specify an annotation/annotation type to an existing key.

Don't really think this is necessary. Trivial to do already:
Key.get(key.getTypeLiteral(), annotation)

[kashike]

It was to provide the opposite of Key#ofType which makes sense to have as it deals with the AnnotationStrategy itself.

There's not a huge difference with changing the annotation, one just involves less duplication:
key.withAnnotation(annotation)
Key.get(key.getTypeLiteral(), annotation)

If you don't think this is necessary, that's fine - feel free to close.

ofType is slightly more necessary, as construction a new variant with a different type requires some branching (to deal with annotation instances vs annotation types).

Personally, the discoverability here is at least a bit of a selling point. More than once I've looked for an ofType() sibling for annotations in Key and realized I need to instead use the factory method.

[sameb]

if you think it's worth it extra methods, feel free to merge in.

Any chance of this being pulled soon, @dimo414?

Any chance of getting this in soon? 😺

Is there a chance of this getting in soon?

I'll take a swing at it over the long weekend :)
