[kartojal]

• Allow the usage of any quote currency for the Aave Oracle with a new config field named OracleQuoteCurrency. This allows to use USD as quote currency instead of ETH.
• Change deployment scripts to support custom quotes
• Allow the deployment scripts to load and deploy custom AToken or RateStrategies.
• Fix tenderly network config at hardhat to support latest plugin.
