Prevents developers from minting bad release NFTs such as those with

1. same version code and different apk.
2. Materially same nft as previous ones. (same apk hash)

Manages the store update process by preventing developers from

1. Submitting same request to update multiple times on store.
2. Submitting app update as new app.

This would basically take effect from the second release after taking this update. First release would only populate the data in the config.yaml file.
