    Copy hieradata on openstack when upgrading

    During the platform upgrade process, we first install the newer version
    of the StarlingX system on the standby controller and after that, we
    swact and install the other controller. When this process happens, the
    puppet plugins are not in place on the newly updated controller since
    the stx-openstack app is installed only on the older version of the
    system. This fix bypasses that behavior by checking for all plugins that
    uses Openstack configuration data, if it is generating hieradata during
    a upgrade process, it will copy those configuration from the older
    version's hieradata folder.

    TEST PLAN
    PASS: Installation from scratch on a new SX server
    PASS: Upgrade from previous version to current development version on SX
    PASS: Upgrade from previous version to current development version on DX
