Align formatting of annotations

[fad3t]

What

This may sound a bit stupid, but I'm wondering if we could align the formatting of the different annotations. Some use hyphens (inodes-threshold, initial-resize-group-by, ..) while other use underscores (storage_limit, pre_capacity_bytes), which can be confusing. The standard seems to be hyphens from what I've seen.

How

Update the few annotations that use underscores and replaces them with hyphens. We might want to support both for some time to avoid breaking changes?

If you're OK with the idea, I'd be happy to contribute.
