This is an architecture change. I would strongly prefer that we do that changes step by step:

1. discuss the mechanism
2. update proto
3. update implementation + tests.

This PR as been split up:

• Documentation (docs: market params design_doc #1152)
• Proto (feat(proto)!: Add MaxCollateralShare, MinCollateralLiquidity, MaxSupplyUtilization #1159)

After those merge, I will take the remaining code in this PR (i.e. the implementation of MaxSupplyUtilization and related calculations), turn them into a small PR, and close this.

seams like we can close now to avoid confusions. You can keep your branch locally.
