Some platforms do not have grub2, and some require other partitions.

Images don't work without these fixes:
* Enable Network Manager.
* Disable cloud-init.
* Add Hyper-V modules into initramfs.
Fixes specific for RHEL:
* Create ifcfg-eth0 required by waagent.
* Install python3 and net-tools required by waagent.
Recommended changes:
* Use recommended kernel boot args.
* Disable kdump.
This is required to ensure that SELinux is configured properly while
building. It fixes the problem with building tar, and should be
installed in the other image types for consistency.

Since these images can be used to create multiple machines, they should
not have a unique machine-id attached to them. Replace /etc/machine-id
with an empty file so that it will be regenerated at boot time.
