Testnet incoming RESET and push on 12/16

Hi all,

We want to give everyone a heads up on the breaking changes in the next testnet release on 12/16.

A major change was landed today - https://github.com/libra/diem/commit/76576974dc47bada937c2851b62060a43fc0bd55.

Due to the breaking nature in the commit, testnet genesis will be reset during deployment. Notably after deployment, there are two currencies in testnet: XUS (stablecoin), and XDX (synthetic currency).
