Custom Image - Repository URL with Port Number

[candidson]

Description

This solves the following issue #729, allowing to use a format such as "my-custom-repository:5000/myterraform/myimage:latest" as custom terraform image. Additionally, this allows optionally install the curl package on the custom image, making it possible to use root-less customer images (such as in openshift per example).
