Description

We need a sub API for storing per Container metadata of Deleted Messages.

Here is the API:

class StorageInformation {
    private final BucketName bucketName;
    private final BlobId blobId;
}

class DeletedMessageWithStorageInformation {
    private final DeletedMessage deletedmessage;
    private final StorageInformation storageInformation;
}

interface DeletedMessageMetadataVault {
    Publisher<Void> store(BucketName, DeletedMessageWithStorageInformation);

    Publisher<Void> removeBucket(BucketName);

    Publisher<Void> remove(BucketName, User, MessageId);

    Publisher<StorageInformation> retrieveStorageInformation(User, MessageId);

    Publisher<DeletedMessageWithStorageInformation> listMessages(BucketName, User);

    Publisher<BucketName> listBuckets();
}

You will provide the API + contract in `mailbox/plugin/deleted-messages-vault`.

You will provide a memory implementation of it in `mailbox/plugin/deleted-messages-vault-memory`
