feat(artifact-registry): add support for code repositories with multiple apps

Closes #65

See merge request !74

Add a variable called `ARTIFACT_REGISTRY_IMAGE_NAME` to allow the names
assigned to images pushed to Artifact Registry to be overridden. This supports
the situation where multiple apps are present in the same source code
repository as the image name can be customised for each app.

fix: getting the latest tag in the changelog expected a space after the square brackets containing the semver. This isn't always the case, so don't assume this

feat(pre-commit): add support for Docker

Closes #62

See merge request !71

Add a docker service to the pre-commit job and appropriate variables to
allow pre-commit jobs to use docker images should they desire.

Since this change involves adding a `before_script`, future-proof
ourselves against jobs wanting to customise the `before_script` section
of the config by making `pre-commit` into a template job. This means
that jobs can *extend* `before_script` using `!reference` tags.

feat(python-tox): allow specifying version of tox

Closes #63

See merge request !72

Add a variable called `TOX_REQUIREMENT` which allows downstream
consumers to override the version of tox installed and used.

Closes #63

feat(terraform-module): allow composition with Auto DevOps modules

Closes #59

See merge request !70

The stock `Terraform-Module` template from GitLab defines its own stages
which are _almost_ compatible with Auto DevOps but not quite.

Issue #59 initially proposed re-working `terraform-module.yml` to be
based on the base template but, really, the only thing that needed to be
done was to move the `fmt` job from the `validate` stage to `test`.

(Arguably `fmt` could be replaced by stuff from
`/auto-devops/terraform-pipeline.yml` but that's for another day.)

Instead of copy-pasting the module, simply import the Auto DevOps stages
and move the `fmt` job.

While we're here, and because this is supposed to be "the One Template
To Rule Them All" for terraform modules, also add in a default
`workflow` template *a la* `common-pipeline.yml`.
