TRC-106 Enable GRAI/LIQ Gauge [Ethereum] (no cap)

Motivation The Liquis community has faced significant challenges in trading LIQ due to the lack of depth of the current pools, resulting in high price impact and slippage. There has been some resistance in providing liquidity with ETH. Users prefer to lock the token inside Liquis in the long run, potentially adding a barrier to adoption due to the severe hurdles in buying and selling LIQ on secondary markets. Such hurdles can be helped by the introduction of a LIQ/GRAI pool which will provide an efficient and more user-friendly trading environment, catering to an increasing demand.
