Oracles are critical for funding. We need to understand the market price of CTDL and the funding assets in order to apply a discount to the CTDL/$ASSET price.
The Funding contract has an oracle, and the state can be updated by keepers via updateCitadelPerAsset()
All CTDL/ASSET oracles ultimately use the MedianOracle as the source of the CTDL/ASSET price. This allows us to concatinate a variety of oracles sources when possible and desired.
