Removed jenkins jobs templates

As an Apertis developer, we want to be able to quickly find definitions
of Jenkins jobs we use so that we can easily fix and update them
without having to edit them scattered all over out CGit instance.

All jenkins jobs templates are moved into apertis-jenkins-jobs git
repository under git.apertis.org.

For the reason that we drop moved templates in this repository.
