[Emergency proposal] Update strategy towards the unpegging of UST

After the last vote, the main Treasury Gnosis safe signers have executed some sell orders.

We are still sitting on 1,117,529 UST which is around 40% of our initial position.

Given the latest announcements from Do Kwon from the Terra project (https://twitter.com/stablekwon/status/1524331171189956609), there is no clear and conclusive plan to save the peg.

This proposal is to give a chance to holders to review their position after this announcement.

The 3 proposed options are:

1. Do nothing: keep our exposure to UST and wait for better days.
2. Liquidate all exposure by Friday 13th May 2022: no matter the loss, liquidate everything at market price from Binance (only liquidity available atm)
3. Reduce exposure by 50% over by Friday 13th May 2022, letting the multisig signers decide on the most opportune time.
