    Adds option to skip overcloud nodes setup

    When baremetal nodes are used, there is no
    need to set up virt nodes. This commit will
    skip setting up overcloud virt nodes if the
    overcloud_nodes variable is empty.

    The source of instackenv.json file is set as
    a variable so a ready file can be imported.
