Replace customize-vm service with boot script

Currently the VM guests are configured on a service added on the
customize-vm script created in the image building process.
There is no real need for the script to run on that context, and it is
easier to manage if it runs as part of the cloud-init context.
This commits:
- Runs the boot script on the cloud-init context.
- Removes it from the images customize-vm scripts.
