Make pipelines less annoying
When scripts/check-feature-categories
is run with no special env vars
set, it will do the existing check: see if the GitLab repo's
config/feature_categories.yml is up to date with the website.
If the CHECK
environment variable is set to 'orphaned', then the script
will check if any of the outdated categories have queues associated to
them. If there are, then these queues are orphaned, because they belong
to feature categories that don't exist on our website any more.
We can run a check for orphaned queues every week, and a regular check less frequently.
