Set MIN_INTEREST_RATE to avoid pool freeze
Summary
Vulnerability Details
The contract has MAX_INTEREST_RATE set but there's no MIN_INTEREST_RATE. This could lead to various functionality of the protocol to stop working for the loan (borrower).
Impact
If the interest rate is set to a very low rate. It could result in various functionalities to stop working.
It will net no protocolFee at all to the protocol (Even though the lender might only earn some interest).
If the interest rate is set to 0 or other low value. It will stop the function from working where the protocolFee is transferred. As, quite a few of the tokens do not allow 0 token transfer.
