    Remove the openvswitch special case upgrade code

    Removed from the tripleo_upgrade_node.sh (major upgrade) & yum_update.sh
    (minor update). The workaround is no longer needed and in fact has the
    opposite effect killing connectitivity to the node. The 'normal' yum
    update on nodes delivers the latest openvswitch 2.6.1 with no drama.

    Also adds a 'complete' message, some extra debug echo for logs
    and removes the python-zaqarclient install no longer needed
