Closes #1282

This PR adds support for using relative weights instead of percentages that need to add up to 100.
The behavior for existing flag configs does not change with this PR, so those will continue to work as they did previously

Nice @bacherfl this is great! I will review thoroughly next week. I think we can merge this, but I don't want to add schema support for it until we have something like #1312 so that we can track the implementation of this across different providers and avoid confusion as to why some flagd and some providers support it and others do not.

I don't think it will be that much work to support #1312. I will follow up next week.

This looks great to me, but I'm going to block it for just a while to see about the feasibility of this, which would help us to release this in a consistent way across multiple implementations.

Consider this approved but temporarily blocked for merge.

@bacherfl @Kavindu-Dodan @thisthat see:

open-feature/flagd-schemas#163
#1321

With these, we will serve fully versioned schemas for flagd, which we can use to denote features and fixes such as the one in this PR.

I'm not doing this afterall. I think it's more maintenance than it's worth, and @aepfli took the time to implement this in most other impls, so I think we can just move forward with this now. I will do the release(s) over the next couple days.
