Merge branch 'build-types' into 'master'

Allow to specify flexible list of types in yaml

First part of flexible pipeline build in GitLab CI

Having following `.gitlab-ci.yml`:
```
types:
- test
- deploy
- notify

rspec:
  script: "rspec"

rubocop:
  script: "rubocop"

staging:
  type: deploy
  script: "echo deploy"
  only:
  - master

production:
  type: deploy
  script: "echo production"
  only:
  - tags

dockerhub:
  type: notify
  script: "curl http://docker/hub/web/hook"

downstream:
  type: notify
  script: "curl http://build/downstream/jobs"
```

GitLab CI will trigger two test jobs in parallel, when finished it will trigged either staging or production, when finished it will trigger dockerhub and downstream in parallel.
