  - Support different format of fuel task info

    As described in this bug: https://bugs.launchpad.net/fuel/+bug/1625518
    json output of the task can be in different format: single dict or list
    of dicts. During tests of https://gerrit.opnfv.org/gerrit/21807 only the
    later one was visible, try to support both types of output.
