Subject: [PATCH] Fix vhd images

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.
