Script to create VMWare Node

This is a bash script to create a new vmware node (ESX). It uses Ansible (along with python pysphere) to create a node from a template. I originally use Cobbler to provision nodes and used Ansible to create a bare vmware node, but the provisioning time was around 15 to 20 minutes, too long for my needs. Cloning from a template made for a provision time of around 5 minutes, reasonable but not stellar. Once the node is created, a remote session is opened (via vmware tools) to configure network settings & trigger a reboot. Once rebooted, the node runs puppet agent to finalize configuration.
