Added the required initialization to start the docker swarm cluster.
Converted yet more dos format files to unix format. Updated the
document on building voltha on a QEMU/KVM virtualization environment
using vagrant. Added a configuration file for the install vagrant to
eventually enable multiple users on a single compute node all able to
run independent voltha docker swarm clusters as VMs. More work is
required to finalize multi-user test mode which will be submitted in a
subsequent update.

This update continues to address Jira VOL-6
