class Upgrade(Operation_upgrade):
    """
    A class to manage package upgrade operations on a remote system using `yum`.

    This class provides functionality to upgrade installed packages on RHEL/CentOS systems
    using the yum package manager. It allows configuration of execution privileges and
    safety guards for package upgrade operations.

    Attributes:
        guard (bool): If `False` the commands will not be executed.
        sudo (bool): If `True`, the commands will be executed with sudo privileges.
        su (bool): If `True`, the commands will be executed with su privileges.

    **Examples:**

    .. code:: python

        # Upgrade installed packages on all hosts
        r = yield Upgrade()
        # Check if the operation was successful
        if r.cp.return_code == 0:
            print("Packages upgraded successfully")

    Usage:
        This class is designed to be used in a generator-based workflow where commands are yielded for execution.

    Notes:
        - Uses `yum upgrade` command internally for upgrading packages.
        - Inherits from Operation_upgrade base class.
        - This operation upgrades installed packages to their latest versions.
