Set Java 8 as the default JDK for all builds

Restore the default settings for Java 8, so that all
existing builds are all getting the same basic variables:
- JAVA_HOME pointint to Java 8 JDK
- PATH having Java 8 by default

Bazel, in the absence of JAVA_HOME, tries to automatically
detect where Java is and use it. After the migration to Debian
Buster which includes both Java 11 and Java 8, Bazel was
getting confused and used the wrong default JDK.

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.
