Import and Write Smart Contracts Necessary to Integrate Maker Allocator SubDAOs to Sommelier Vaults and other ERC4626 Vaults

[0xEinCodes]

Core changes:

This PR encompasses the integration of MakerDAO / Allocator SubDAOs and Conduits into Sommelier cellars via the use of Conduits from MakerDAO && SparkProtocol, and possibly an modified version of the ArrangerConduit.sol from MakerDAO.

Initially the design of this adaptor encompassed writing a custom ERC4626Conduit.sol file, that is now commented out into ERC4626Conduit.nc (it is unfinished). ArrangerConduit.sol was seen as a already made smart contract that integrated well into Maker's "EndGame" Permissioned setup / architecture.

The only parts of the ArrangerConduit.sol that may need customization are including actual external calls into destination contracts to actually draw and return funds back to the buffer for a respective allocator.

Currently, this PR is in the discussion and design phase.

TODO

• Review MakerDAO EndGame content (videos, docs, forum posts)
• Review conduit codebases (MakerDAO and Spark repos)
• Discuss the next steps on the preferred design for an erc4626 conduit for MakerDAO ecosystem
• Implement
• Test
• Peer Review
• Audit
