rel_eng: Add release engineering scripts into ghc tree
It is better to keep these scripts in the tree as they depend on the CI
configuration and so on. By keeping them in tree we can keep them
up-to-date as the CI config changes and also makes it easier to backport
changes to the release script between release branches in future.
The final motivation is that it makes generating GHCUp metadata
possible.

ci: Don't use complicated image or clone in not-interruptible job
This job exists only for the meta-reason of not allowing nightly
pipelines to be cancelled. It was taking two minutes to run as in order
to run "true" we would also clone the whole GHC repo.

Add scripts to generate ghcup metadata on nightly and release pipelines
1. A python script in .gitlab/rel_eng/mk-ghcup-metadata which generates
suitable metadata for consumption by GHCUp for the relevant
pipelines.
- The script generates the metadata just as the ghcup maintainers
want, without taking into account platform/library combinations. It
is updated manually when the mapping changes.
- The script downloads the bindists which ghcup wants to distribute,
calculates the hash and generates the yaml in the correct structure.
- The script is documented in the .gitlab/rel_eng/mk-ghcup-metadata/README.mk file
1a. The script requires us to understand the mapping from platform ->
job. To choose the preferred bindist for each platform the
.gitlab/gen_ci.hs script is modified to allow outputting a metadata
file which answers the question about which job produces the
bindist which we want to distribute to users for a specific
platform.
2. Pipelines to run on nightly and release jobs to generate metadata
- ghcup-metadata-nightly: Generates metadata which points directly to
artifacts in the nightly job.
- ghcup-metadata-release: Generates metadata suitable for inclusion
directly in ghcup by pointing to the downloads folder where the
bindist will be uploaded to.
2a. Trigger jobs which test the generated metadata in the downstream
`ghccup-ci` repo. See that repo for documentation about what is
tested and how but essentially we test in a variety of clean images
that ghcup can download and install the bindists we say exist in our
metadata.

+# fetch-gitlab-artifacts
+
+This script is used to fetch and rename GHC binary distributions from GitLab
+Pipelines for upload to `downloads.haskell.org`.
+
+## Workflow
+
+1. [Configure]() a `python-gitlab` profile for <https://gitlab.haskell.org/>:
+ ```
+ $ cat > $HOME/.python-gitlab.cfg <<EOF
+ [haskell]
+ url = https://gitlab.haskell.org/
+ private_token = $PRIVATE_GITLAB_TOKEN
+ ssl_verify = true
+ api_version = 4
+ EOF
+ ```
+1. Push a release tag to ghc/ghc>
+1. Wait until the CI pipeline completes
+1. Run `fetch-gitlab -p $PIPELINE_ID -r $RELEASE_NAME` where `$PIPELINE_ID` is
+ the ID of the GitLab release pipeline and `$RELEASE_NAME` is the name of the
+ GHC release (e.g. `8.8.1` or `8.8.1-alpha1`)
+1. The binary distributions will be placed in the `out` directory.

+# mk-ghcup-metadata

+This script is used to automatically generate metadata suitable for consumption by
+GHCUp.
+
+# Usage
+
+```
+nix run -f .gitlab/rel_eng/ -c ghcup-metadata
+```
+
+```
+options:
+ -h, --help show this help message and exit
+ --metadata METADATA Path to GHCUp metadata
+ --pipeline-id PIPELINE_ID
+ Which pipeline to generate metadata for
+ --release-mode Generate metadata which points to downloads folder
+ --fragment Output the generated fragment rather than whole modified file
+ --version VERSION Version of the GHC compiler
+```
+
+The script also requires the `.gitlab/jobs-metadata.yaml` file which can be generated
+by running `.gitlab/generate_jobs_metadata` script if you want to run it locally.
+
+
+## CI Pipelines
+
+The metadata is generated by the nightly and release pipelines.
+
+* Nightly pipelines generate metadata where the bindist URLs point immediatley to
+ nightly artifacts.
+* Release jobs can pass the `--release-mode` flag which downloads the artifacts from
+ the pipeline but the final download URLs for users point into the downloads folder.
+
+The mapping from platform to bindist is not clever, it is just what the GHCUp developers
+tell us to use.
+
+## Testing Pipelines
+
+The metadata is tested by the `ghcup-ci` repo which is triggered by the
+`ghcup-metadata-testing-nightly` job.
+
+This job sets the following variables which are then used by the downstream job
+to collect the metadata from the correct place:
+
+* `UPSTREAM_PIPELINE_ID` - The pipeline ID which the generated metadata lives in
+* `UPSTREAM_PROJECT_ID` - The project ID for the upstream project (almost always `1` (for ghc/ghc))
+* `UPSTREAM_JOB_NAME` - The job which the metadata belongs to (ie `ghcup-metadata-nightly`)
+* `UPSTREAM_PROJECT_PATH` - The path of the upstream project (almost always ghc/ghc)
+
+Nightly pipelines are tested automaticaly but release pipelines are manually triggered
+as the testing requires the bindists to be uploaded into the final release folder.

+In any case the script takes the same arguments:
+
+
+* --metadata: The path to existing GHCup metadata to which we want to add the new entry.
