Adding extra annotations to service

[matthewkrupnik]

Proposed changes

Currently there is a way to add extra label to the nginx-ingress-controller service, but not annotation.
Why annotations? One example is when using MetalLB if you want services to share same IP you have to add an annotation for that.

This would likely be useful for a very small amount of people, but if operator allows extra labels, why not also support annotations?

What's the reluctance with merging this PR? It's been sitting around for 3 months with no feedback at all. All tests are passing, change in minor and there are no comments good or bad. What do I need to do to get some eyes on this?
