    """BackupService class is a subcommand that will contain other commands to configure the service as well as manage
    it. This approach attempts to make the interface more intuitive by keeping a hierarchical structure where the
    service can have all its options under one command instead of having multiple completely separate commands (e.g
    settings-backups, manage-backups and repository-setup-backup.)

    The idea is that the interface will look like:
    couchbase-cli backup-service [settings | plans | repositories | cloud-credentials] where each element in [] is a
    subcommand to manage those options for that part of the backup service. As such if the user is not sure of what they
    want to do they can always do couchbase-cli backup-service -h to get a top level details and then move down the
    hierarchy to a more concrete option.
