Allow extra Labels to be specified like the Annotations about vitess-operator

@henders Thanks for confirming!

@evalsocket It sounds like #7 should be a good template for this then. The author of that PR (@avaidyanatha) can help if you have any questions about it.

I like this idea. You're right that it will probably look very similar to the existing custom annotation support. Would you be interested in working on this by chance? :)

[henders]

I was debating this alright... I'm trying to find how I can free up some of my time! :)

@enisoc @henders Would like to work on this. Can this be assigned to me?

[enisoc]

@evalsocket That would be great if you're interested in working on this! We should just make sure to agree on the design first.

@henders If we expanded the API to additionally have a labels field in all the places where we currently have an annotations field, would that satisfy your use case?

If so, then it should be very analogous to #7, just with labels instead of annotations.

[henders]

That would be great. And yes, adding a labels field everywhere there is an annotations field would absolutely solve our usecase!
