[Non-Constitutional] Pilot Stage: Treasury Backed Vaults research and development

I voted FOR this proposal at the temp check stage. Re-sharing my feedback below.

I like this proposal for a couple of reasons:

* It creates an avenue for the DAO to directly use Arbitrum protocols, which I think is a win-win.
* It creates an avenue for the DAO to access stablecoins, which I think is important for DAO ops and treasury diversification.

Some potential concerns to consider:

* The DAO will need to have an alternative source of stables available to pay off the debt per the concern of @GFXlabs. I don’t think the DAO can sell ARB for stables fast enough via governance for this use case.
* Moving DAO ARB into DeFi protcols introduces additional risk to governance. I’d like to have a robust plan for mitigating risk (cap on total ARB deposited, plan for gradually increasing TVL, audits, etc.)
