Remove .gitcookies and switch to .netrc for Gerrit authentication

Align the gerrit-release pipeline with other Jenkins jobs by replacing
the use of `.gitcookies` with `.netrc` for Git authentication against
gerrit.googlesource.com.

Instead of uploading a full `.gitcookies` file to Jenkins credentials,
the pipeline now injects the Gerrit username and password via standard
Jenkins `usernamePassword` credentials and writes them to
`$HOME/.netrc`.  Git automatically uses this file when cloning or
pushing over HTTPS.

This simplifies credential management and ensures consistency across all
Gerrit-related Jenkins jobs.

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 --require-hashes 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.
