How to set up and validate locally

1. Create .gitlab-ci.yml with:

test_with_expire_in:
  script:
    - echo "Testing with expire_in" > test.txt
  artifacts:
    expire_in: 2 hours
    paths:
      - test.txt

test_without_expire_in:
  script:
    - echo "Testing without expire_in" > test2.txt
  artifacts:
    paths:
      - test2.txt

2. Run the pipeline and let it complete successfully
3. Find the two jobs:
   1. job1 = Ci::Build.where(name: 'test_with_expire_in').last and
   2. job2 = Ci::Build.where(name: 'test_without_expire_in').last
4. Check a few things for each of these jobs:
   1. job1.options -> this will give us what's in the yaml, which in this case will be 2 hours
   2. job2.options -> this will be nil
5. job1.job_artifacts.first&.expire_at -> This should be 2 hours (YAML!)
6. job1.job_artifacts.first&.expire_at -> This should be 30 days (which is the instance default)

Repeat steps 2-6 on master.
