Add Image Customization Parser for VMware vSphere Hypervisor Support.

This is the first changeset submitted as a part of project to
add cloud-init support for VMware vSphere Hypervisor. This changeset
contains _only_ the changes for a simple python parser for a
Image Customization Specification file pushed by VMware vSphere
hypervisor into the guest VMs. In a later changeset, will be submitting
another patch to actually detect the underlying VMware vSphere hypervisor
and do the necessary customization.

+# and should not be changed by those layers. It's up to the in-guest engine to

+# interpret and materialize the user's request.
