Correct previous patch on fuel rework

Correct previous patch on fuel rework

Some leftover chars in https://gerrit.opnfv.org/gerrit/#/c/24901/
were keeping the deploy to work.
Also, the empty folder networks was added. This folder should contain templates
for virtual network config for the targets. For arm we don't need those so we
leave it empty for consistency with other projects and for avoiding changing
the deploy logic
