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.
