If a task name matches a stage name, make the stage default to the task name

Summary

In .gitlab-ci.yml, it seems redundant to have to specify a stage when the task names themselves are self-descriptive. e.g.:

stages:
- build
- test
- release
- deploy

build:
  stage: build
  script:
    - docker build -t $CONTAINER_TEST_IMAGE .
    - docker push $CONTAINER_TEST_IMAGE

test:
  stage: test
  script:
    - docker run $CONTAINER_TEST_IMAGE /script/to/run/tests

release:
  stage: release
  script:
    - docker tag $CONTAINER_TEST_IMAGE $CONTAINER_RELEASE_IMAGE
    - docker push $CONTAINER_RELEASE_IMAGE
  only:
    - master

deploy:
  stage: deploy
  script:
    - ./deploy.sh
  only:
    - master

In the above example, I'd like to be able to leave out the stage, but if I do that, I believe it'll default to the test stage for every task.

Possible fixes

Rather than default the stage to test, check if the task name matches any of the stages first, and default to the matching name.
