Code Issues Proposed changes

Utilize Ubuntu's hardware enablement stack for trovestack 

This brings in the latest fixes which is often important for
nested virtualization.  It is required for ppc64el.  This stack
is installed via a new post-install.d script in the trove
integration element ubuntu-xenial-guest.

A user that is manually creating datastore images may install
this stack by setting the following environment variable prior
to running the disk-image-create command.

export DIB_USE_HWE_KERNEL=true
