I have a suggestion for the title of this PR:

feat(webhooks): pass webhook-* annotations to webhook providers

[Raffo]

@mloiseleur yes, 100% happy to add more info. I was more wondering "is this enough" and hence why I opened it like this. I'd say that it looks enough and I'm kind of embarrassed I didn't think about it when I first worked on the webhook. Do you see anything that needs to be added for this feature to satisfy the original issue?

[Raffo]

@mloiseleur added some docs.

[mloiseleur]

Nope. /lgtm
