Farm Volume/Liquidity Limits

I propose to set a threshold for farms to earn CAKE after a certain amount of time. If a farm's liquidity is below a certain amount or if the volume of that trading pair is below a certain amount for a month (or some peroid of time), then that farm should be removed.

There are a few farms with 200-300% APR with liquidity around $500,000 or less and very little 24 hour trade volume. Although these farms have a small multiplier, they could be completely removed.

As a result, the CAKE per block originally going to these farms could either be reallocated to other farms, burned, added to the lottery, or used as part of the profile rewards/NFT gamification which could be later voted on.
