Make GID used by docker on host configurable

The group ID of docker had to be known to make docker accessible to
Jenkins. So far the GID was hardcoded. Since the GID was different on
different hosts, this required to rebuild the master image for each
host with different GIDs used by docker.

Now the docker GID is configurable, when starting up Jenkins by setting
the DOCKER_GID environment variable in the docker container.

Providing jobs

This project uses Jenkins Jobs Builder [1] to generate jobs from yaml descriptor files.

To add new jobs reuse existing templates, defaults etc. as much as possible. E.g. adding a job to build an additional branch of a project may be as easy as adding the name of the branch to an existing project.

To ensure well readable yaml-files, use yamllint [2] to lint the yaml-files. Yamllint can be downloaded using Python Pip:

pip3 install yamllint

To run the linter, execute this command from the project's root directory:

yamllint -c yamllint-config.yaml jenkins/**/*.yaml

Yamllint will not fix detected issues itself.
