    create history for the overcloud deploy command

    Add a history directory in user $HOME for tracking
    all the calls of the openstack overcloud deploy command
    passed by the users.
    Each deploy command run by a user is now track in an history file under
    $HOME/.tripleo directory.
    It allow to retrieve all the previous calls from
    the openstack overcloud deploy command, the environment files used and the
    templates directories used, for analysis, debugging or tracking. See
    https://bugs.launchpad.net/tripleo/+bug/1673700

    It will be very usefull for post deployment user experience and
    for customer debuging.

    This review aim to be backport for old releases support.
    I will implement a mistral workflow in a follow up review for
    Pike, as suggested by D0ugal (D Matthews)
