All the changes for minimum/maximum were not there before, hence they are getting reported as broken changes (even though new ranges are bigger than the limits we enforced before)

We could also remove these range changes to avoid breaking errors, no preference.

Consult with @FumingZhang, but IMO it's OK to add these as they are bigger than the old actual limits enforced by the old RP. Also happy to remove if we don't want to deal with breaking change pain it adds, but if we do decide to remove we should consider putting it into the documentation manually what the min/max values are.

There will be more changes to custom node config in the coming months, I could add all the limitations to swagger then, to avoid adding it only to select few parameters.

So now I'd remove them for easier merge of those changes and re-add them with new changes in the coming months, thoughts? @matthchr @FumingZhang

We should in theory be able to get this merged without too much issue as is, IMO. But really defer to what @FumingZhang thinks/wants here. My 2c is keep them.

I think it's ok to have such a breaking change, will go through the breaking change review once I create the PR based on the dev branch later.
