Use Debian buster as docker image base

This change adds support for Java 11, keeping Java 8 for now
as a default, for not breaking compatibility with existing builds.

The set-java.sh utility allows to switch between Java 8 and Java 11,
enabling the full E2E testing of Gerrit in a pure Java 11 environment
also outside of a Bazel execution.

Adapt the other components of the build to the new packages provided
by Debian buster.

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.
