This patch adds the possibility to process the output of the jobs.
There are two ways to do that:

1. Define a reusable Output Template = an ERB template that with the help of variable @output can process the job output.
2. Define a Runtime Template = as indicated in the name, users can define the template on the runtime by filling in a text field in the wizard.

On top of that, it is possible to set default Output Templates for a Job Template, meaning it would be selected directly when selecting a new Output Template.

Let me add 'How to use' screenshots.


Now, when executing the job, there are new fields in the wizard:


^ There is a slight change now - users can define only one Runtime template. Therefore users do not have to submit:)
When you want to see the output of the job, navigate to the "Processed tab":

This patch will show Runtime templates in the "default Output Templates" multi-select field. A solution for not showing these would be a part of a patch to the Foreman repo.
