Cleanup F5 configuration

Head back to the .gitlab-ci.yml file and add a final stage of delete, so that the section looks as follows:

stages:
  - registry
  - container
  - info
  - test
  - staging
  - delete

Add the following details for the staging block to the end of the file:

delete_config:
  stage: delete
  rules:
    - if: '$CI_COMMIT_BRANCH == "delete"'
      when: manual
  tags:
    - ansible_f5
  image: ${CI_REGISTRY}/${CI_PROJECT_PATH}/ansible:latest
  script:
    - echo $ANSIBLE_VAULT_PASSWORD > vault_passwd
    - ansible-playbook -i inventories/staging/ --vault-password-file vault_passwd bigip-delete-configuration.yml

Commit the changes. This will trigger another pipeline run, but we can ignore it.
