Update cUSDT interest rate model

Thanks for your contribution @arr00 :+1:

Before voting 20th proposal, I’d like to check how to work this code.(actually, who is calling this contract)

I’m not a smart contract developer so I just depends on its rationale/discussion and evidence to cast a voting on specific proposal. I’d like to understand its working process thoroughly as possible as I can.

I understand and agree the intention to achieve with this proposal. (I think that making standard for stable coins is good idea)

But I don’t understand how to apply it (technically)

For technical side, I thought that there is some PR to replace the existing interest rate model contract address to this new one.

Which code will actually set up this new interest rate model contract address?

and I’m not sure how many dev review this contract code.
Does it some evidence(some comments for codes reviews) this code was taking enough code review?
