Epic: NFT Metadata editor

[julien51]

On Discord, more and more users are asking for our help to fully customize the NFT metadata "on OpenSea". We should consider allowing these metadata (title, image, description... and more later) to be customized from the dashboard, both on a "per lock" basis (we already allow this for the image...) and a per key basis.

We should start with the simplest version (per lock customization of the title and description...), then allow for per key changes.

Once this is out of the way we should let users upload the metadata items to IPFS from our dashboard and pin it using Pinning services like IPFS, nft.storage... etc.

Another idea would be to reach out to tools that allow for generations + saving of the metadata like https://nft-generator.art/ or https://nft.bueno.art/

I think we can do this. I added APIs for updating metadata for keys and locks earlier on v2 endpoints. We can use those assuming that's what the default token URI points to.
