        Create or update the ACL for ``username``. If the user already exists,
        the existing ACL is completely overwritten and replaced with the
        specified values.

        ``enabled`` is a boolean indicating whether the user should be allowed
        to authenticate or not. Defaults to ``False``.

        ``nopass`` is a boolean indicating whether the can authenticate without
        a password. This cannot be True if ``passwords`` are also specified.

        ``passwords`` if specified is a list of plain text passwords
        to add to or remove from the user. Each password must be prefixed with
        a '+' to add or a '-' to remove. For convenience, the value of
        ``passwords`` can be a simple prefixed string when adding or
        removing a single password.

        permissions. Each string must be prefixed with either a '+' to add the
        category permission or a '-' to remove the category permission.

        ``commands`` if specified is a list of strings representing command
        permissions. Each string must be prefixed with either a '+' to add the
        command permission or a '-' to remove the command permission.

        ``keys`` if specified is a list of key patterns to grant the user
        access to. Keys patterns allow '*' to support wildcard matching. For
        example, '*' grants access to all keys while 'cache:*' grants access
        to all keys that are prefixed with 'cache:'. ``keys`` should not be
        prefixed with a '~'.

        ``reset`` is a boolean indicating whether the user should be fully
        reset prior to applying the new ACL. Setting this to True will
        remove all existing passwords, flags and privileges from the user and
        then apply the specified rules. If this is False, the user's existing
        passwords, flags and privileges will be kept and any new specified
        rules will be applied on top.

        ``reset_keys`` is a boolean indicating whether the user's key
        permissions should be reset prior to applying any new key permissions
        specified in ``keys``. If this is False, the user's existing
        key permissions will be kept and any new specified key permissions
        will be applied on top.

        ``reset_channels`` is a boolean indicating whether the user's channel
        permissions should be reset prior to applying any new channel permissions
        specified in ``channels``.If this is False, the user's existing
        channel permissions will be kept and any new specified channel permissions
        will be applied on top.

        existing passwords and the 'nopass' flag from the user prior to
        applying any new passwords specified in 'passwords' or
        'hashed_passwords'. If this is False, the user's existing passwords
        and 'nopass' status will be kept and any new specified passwords
