dockerctl start all does not work with systemd

[Matthew Mosesohn]

dockerctl start all results in the following:
Failed to issue method call: Unit docker-all.service failed to load: No such file or directory.

It should instead call all the containers one at a time. This is a regression from behavior we had in Fuel 7.0.

    Fix `dockerctl start all' not working with systemd

    There is a missing local variable assignment for "$container" in
    ./files/fuel-docker-utils/functions.sh. Instead an environment
    variable leaks from /usr/bin/dockerctl into functions.sh's
    start_container and it tries to start unit "docker-all" which
    obviously does not exist.

    This patch assigns the first argument of start_container to a
    local variable "$container" which fixes this regression.

    This bug cannot be reproduced on stable/8.0. It can be triggered
    least in fuel-9.0-liberty-195.
