YIP-81: Remove Strategic Assets from YDS

See the forum post here for the full post and discussion: https://forum.yam.finance/t/yip-81-remove-strategic-assets-from-yds/1513

Basic Summary

Restructure the Yam DAO Set so that it does nor include our strategic assets.

Abstract

I propose that we limit the assets within the Yam DAO Set to only those that can be easily re-balanced without worrying about strategic uses. This would change the current YDS make-up to only include ETH, Stables, DPI, and WBTC. The SUSHI, UMA, and INDEX included in the set now would be moved into the treasury proper with the rest of those tokens Motivation

Advantages:

• This simplifies the re-balancing process for the Treasury and moves the onus of rebalancing our strategic assets to the larger treasury management process.
• It will be easier for anyone to buy this SET since we can use NAV issuance to allow buyers to enter with one asset.
• If YDS that does not contain the tokens of projects that we are working with, it will have a larger addressable market and could be marketed to DAOs as a simple diversified treasury management tool.

Specifications

Remove the specified assets from the Yam DAO Set. This may entail selling to ETH to exit, and re-buying the assets for the treasury. Some assets may not need to be re-bought if YIP-80 passes, as they are already above our desired allocation percentages.

Current Strategic assets in the YDS: ~ 1810 INDEX - could be sold for USD if YIP-80 passes ~ 2930 SUSHI - could be sold for USD if YIP-80 passes ~ 1552 UMA - moved to Treasury

Assuming both proposals pass, this will be done in conjunction with the treasury re-balancing.
