1 month top-up for Polkadot Hydration farms

This proposal is part one of THREE referenda that will make relevant changes to the ongoing Polkadot Hydration farms including a 1 month top-up, adjustments to some of the existing farms and the launch of two NEW farms. If approved, together the three referenda will:

Maintain existing APR on:

• USDC/ USDT 2-Pool
• DOT
• vDOT
• ASTR
• GLMR
• BNC
• PHA
• MYTH/ DOT

Adjust APR on:

• CFG - reduce yield per period by 25%
• INTR - no further rewards, farm to close once current rewards run dry
• KILT - reduce yield per period by 50%
• vASTR - reduce yield per period by 50%

Launch new farms:

• tBTC - up to 200% APR, targeting 30% APR on $2,222,222 liquidity
• AAVE - up to 250% APR, targeting 25% APR on ~$1M liquidity

This first referendum must execute first, and transfers vDOT & HDX to the relevant farms listed above (excluding vASTR, INTR & the new farms).

The second referendum will create the AAVE & tBTC new global farms and adjust parameters of CFG, KILT & vASTR.

The final referendum will create the yield farms for AAVE & tBTC (vDOT & HDX) and they will be live.

The referenda will be staggered to ensure that they execute in this order based on track lengths & support curves :D
