TAP-31: Adjust RBS Capacity

Snapshot note: due to community feedback, the original poster (Nicnombre on the forum) has agreed to adjust the parameter change votes to 0%, 50%, and 80% capacity reduction

The purpose of this proposal is to bring RBS to a state in which it operates as it is meant to: providing challenging, but not insurmountable, liquidity in a range. The current parameters, which offer 10% of supply on the upper wall and 1% daily emittance in the upper cushions, is too extreme to accomplish the aforementioned goal. It also provides a large source of liquidity which could be abused by a malicious actor.

I feel this change is urgent, and I am trying to push a governance timeline that reflects that. Considering more harm can be done by a too-funded RBS system versus a not-funded-enough system, I suggest a liberal capacity change now that may be reverted or augmented in the days and weeks that follow. Keep in mind that, though RBS launched over a year ago, this is the first time the upper range has been tested. I see this as similar to a launch day problem, though the process of fixing it is more tenuous than it might have been day one.
