stack.sh on Ubuntu failed when trying to restart redis service

[Ilya Tyaptin]

When we install devstack with ceilometer and use redis for ceilometer coordination (CEILOMETER_COORDINATION_URL is redis url) then command sudo /usr/sbin/service redis restart are failed[1]. It happens because in ubuntu service are named as redis-server.

[1] Traceback:
