Bash scripts for remote host deployment

Bash scripts for remote host deployment

JIRA: N/A

Adds various scripts into hostscripts/ to make the deployment
easier.
The whole hostscripts directory is copied to the remote host during
deployment.
mkDisks will create needed virtual disks
vncAllow punches a hole in the firewall to allow a vnc connection
    (useful for debugging)
ipnat.sh uses iptables to NAT out an isolated virtual machine
    to access horizon, for example
