First version of jenkins' job to deploy cluster

First version of jenkins' job to deploy cluster

As for now this script can make VMs, Volumes and Networks
in libvirt. Also it manages subnets in order to achieve
zero crossing between them. Fuel master node gets dynamic
network parameters from script by injection during bootloader
stage. Public network being injected in Fuel-master node,
so it can be accessible from network. Cluster's network
is configured with apropriate values.

Included changes in nailgun network & settings configuration.

All data is visible in the summary message.

Thanks devops team for scancodes.py
