New OTC ubuntu images build from OTC ImageFactory

Introduction

Currently OTC offers ubuntu images for ubuntu trusty and xenial.
Found as public images in OTC Image Management Service.

trusty:  Community_Ubuntu_14.04_TSI_latest
xenial:  Community_Ubuntu_16.04_TSI_latest

These images are directly delivered by Canonical to OTC with some base customization for OTC platform.

===

To get ubuntu more adapted to OTC and handled more in line with all the other OTC images,
we decided to build ubuntu images in our internal OTC ImageFactory build tool.
More information about OTC ImageFactory can be found at https://imagefactory.otc.t-systems.com.

This results in some differences to the current images.
Not to break customer workflows when using the existing ubuntu images,
the newly built ubuntu images will
be availavle as public images in OTC Image Management Service with as

trusty:  Standard_Ubuntu_14.04_latest
xenial:  Standard_Ubuntu_16.04_latest
