    """Create a registry helper object from a uri.

    This function parses the URI and determines which supported registry it
    belongs to. It then creates a registry helper object for that registry.
    The supported remote registry types are:
    - Azure Container Registry
    - Google Container Registry
    - AWS Elastic Container Registry

    The format of the URI is as follows:
    - Azure Container Registry: <registry-name>.azurecr.io/<repo-name>/<image-name>
    - Google Container Registry: <location>-docker.pkg.dev/<project-id>/<repo-name>/<image-name>
    - AWS Elastic Container Registry: <account-id>.dkr.ecr.<region>.amazonaws.com/<repo-name>/<image-name>

    Our classification of the registry is based on the domain name. For example,
    if the uri contains `.azurecr.io`, we classify it as an Azure
    Container Registry. If the uri contains `.dkr.ecr`, we classify
    it as an AWS Elastic Container Registry. If the uri contains
    `-docker.pkg.dev`, we classify it as a Google Artifact Registry.

    This function will attempt to load the appropriate cloud helpers for the

    `https://` prefix is optional for all of the above.
