[ARFC] GHO Steward: Agile Parameter Changes

Thank you, @MarcZeller for your thoughtful comments.

Agility is a known limitation of decentralized governance; however, we feel that decentralized community involvement is paramount for the long term success of GHO and has functioned well for many years for the Aave Protocol governance.

At the TEMP CHECK, we received positive sentiment from a number of contributors to the DAO, and we have implemented the majority of these suggestions in this ARFC.

We are comfortable with any outcome of the Snapshot vote and welcome alternative governance solutions that the community may propose.
