image_template: allow to setup template version name

Allow to create templates with the same name but with different version by setting up the `template_version_name` variable. Creating a new version requires the base template to exist. If not specified the value of the variable is `base version` which is the default value for base templates. Signed-off-by: Miguel Martín <[email protected]>
