    Deal with py2-py3 payload switch during upgrade-charm

    Switch to using the default upgrade-charm handler as provided
    by charms.openstack and associated layers.

    This ensures that the payload execution switch from py2->py3
    at OpenStack Rocky is implemented during the charm upgrade
    process.
