Feat: Review contract metadata strategy and relevance

Current store_contract_metadata add additional contract metadata but this can be technically encapsulated within the DAO implementing the proposal and is orthogonal to both store_blob and store implementations in the factory.

Need to create a design doc on use cases and strategy moving forward. Might want to add this to the new sputnik improvements in the modular implementation of sputnik

Although this is something that can be made discoverable through an indexer, the convenience method of adding this on chain does seem like a good option as it's similar to what we do for contract metadata of DAOs. @ilblackdragon would love for this to be reconsidered or open to your thoughts.
