Storage store

[amimart]

Implement the store action of the storage provider.

Details

The storage.Proxy allowing the implementation of a custom storage provider shall provide a base implementation of the store action that will ensure the requested resource's governance allows the action before calling the specific implementation.

To do so the requested resource's governance have to be retrieved through the dataverse and then queried.

The implementation should return, as a result, DigitalResourcePublicationCredential signed using the managed service's key. It'll be the responsibility of the caller to submit it to the dataverse.

The corresponding http endpoint shall be implemented as well.
