Missing working address for ethOracle

Summary

In StableOracleDAI.sol the variable ethOracle is supposed to be set inside the constructor. However no real value is ever set.

Vulnerability Detail

Currently the constructor has this:
ethOracle = IStableOracle(0x0000000000000000000000000000000000000000); // TODO: WETH oracle price
with the incomplete constructor the protocol will not work because ethOracle will fail in its current state.

Impact

Protocol will not work

Recommendation

Finish setting a valid address for ethOracle by finishing the TODO that was already in place.
