Follow up to FIP-21: Approve FRAX-DAI as first G-Uni pool

After the approval of FIP-21 which can be seen here: https://snapshot.org/#/frax.eth/proposal/QmY1YtoDrk4BvQi8Muz2btPNSTHmGbQVfiAVCmFDF7njK9

I propose to start off with FRAX-DAI as first G-UNI pair. This way we can compare its performance compared to the FRAX-USDC UNIv3 pair and decide whether or we want to move that pair over as well in time, if it turns out to deliver increased performance.

Voting Options: Yes, Approve FRAX-DAI as first G-UNI gauge and unlock current FRAX-DAI UNI pool to allow people to move over once implementation is ready. No, do nothing
