Everytime we push a new commit to a branch, a new pipeline is created.
Often the pipeline for the previous commit has not finished yet, and
GitLab does not automatically cancel it. It consumes valuable build
time, even if we don't need the results anymore.
Adding a MR pipeline job to search for previous pipelines on the same
branch and cancel them explicitly.

For a given project all artifacts may be deleted. This was needed due to
space limitations on the gitlab server.

The script has mostly been copied from alphaplan_fwr.py, but with
different input data.

Adding a job to the CI-test environment for testing this.

This script has mostly been copied from alphaplan_fwr.py, but with
different input data (artifacts from the SoftwareStore deploy job) and
without actually importing the data to the Alphaplan database.

Rename all stages to uppercase on this occasion, since we're adding
stages with names containing multiple words.

isort is a Python utility to sort imports alphabetically, and
automatically separated into sections and by type.

Customer specific manifest projects can now set the RELEASE_SUFFIX
variable, which then gets appended to the deployment folder names.

Otherwise it can be assumed that it might be correlated with
outputdir_local, which is not the case.

- Make output-dir an argument that can be passed multiple times instead
  of hard-coding two dirs with certain meanings.
- Remove LOCALDIR variable from package.env, because it is not used
  anywhere (only occurence was job class ".uploadsdkftp" which wasn't
  used anywhere either).

Improve readability of package_release.py and its submodule
generate_release_metadata.py.

- Add describing comments throughout the file.
- Remove duplicate code from functions. Simplify them, so that they do
  what their names say (and nothing more).
- Rename variables and function arguments to make their purpose clearer.
- Harmonize variable names with their corresponding command line arguments.
- Add pydoc for functions.
- Add type declarations to function arguments.
- Generate MD5 and metadata files in the source directories so that they
  can be copied along with the rest of the files.

Trying to query CI variables on a project which does not have the CI
feature enabled leads to an HTTP 403 (forbidden) error.
Check whether CI is enabled using the "jobs_enabled" flag.

- Use "source" and "target" terminology in the script, just like in the
  GitLab CI variables.
- Spefify data types for function arguments.
- Rename function arguments to better reflect their data types.
- Move determination of integration branch into main function, so that
  the successfull status message can be more verbose.
- Remove parent_merge_request feature and checking for gitlab-ci
  integrations, because the check job does not run on gitlab-ci
  integration branches at all.

TypeError: 'NoneType' object is not subscriptable

Example:

Previously we integrated all projects into the manifest, even those that
belonged to a different manifest branch. That led to all manifests
having the same project revisions, even if they should be different due
to different intgrated project branches.

Save a list of integration sources for each manifest branch separately
now, so that we can check which project belongs to which manifest branch
later.

We need to pass the correct target branch to the merge request creation
instead of using the project's default branch.

We have deleted the original project due to git corruption. Replace with
the new project's ID.

Instead of getting the projects from the manifest file, search them via
their INTEGRATION variable.

Improve log messages on this occasion: print URL instead of just IDs.

Add different integration jobs for different manifest branches. The
merge stage only has one job for each manifest, though, because
otherwise we cannot guarantee a consistent state for all branches.

Extend the deploy script for this purpose, so that it can deploy to
multiple manifest branches at once.

We were passing the complete TemporaryDirectory object to the repo clone
function instead of just the path string, resulting in the repo being
cloned into a local dir "<TemporaryDirectory '/tmp/tmphwakypf8'>".

Fix this to actually use the generated temp dir.

This change makes it necessary to keep the TemporaryDirectory object
reference until we don't need the directory anymore, otherwise it will
be removed immediately.

Get targets dynamically using the INTEGRATION variable instead.

This makes it possible to retrigger jobs that are not part of the
given pipeline but in any nested child pipeline of it.
