Previous implementation of command "fuel2 node create-vms-conf"
didn't allow using list of dicts for --conf parameter. It required
to use multiple arguments like:
--conf '{"id": 1}' '{"id": 2}'
which is non obvious for user and inconsistent with UI (in UI
user sees list of dicts).
This patch introduces new possibility to pass parameters
as json list:
--conf '[{"id": 1}, {"id": 2}]'
