Usage with Travis CI `stage` and `jobs` feature

Hi,

I would like to implement the package-lock.json support with Greenkeeper, however, I would like to use the courses with the conditions to be able to optimize the build.

Currently, my travis.yml looks like this:

language: node_js

node_js:
  - 10
  - 9
  - 8

notifications:
  email: false

cache:
  directories:
    - ~/.npm

script:
  - npm run build -- --noEmit # test typescript
  - npm run test # run test
  - npm run coverage # run coverage

branches:
  only:
    - master
    - dev
    - /^greenkeeper.*$/

jobs:
  include:
    - stage: deploy
      if: branch = master # only deploy the code that is on master
      script:
        - npm run build # build TS
        - npm run release # run release process

I was wondering if it was possible to do something like, using stage & jobs and conditional build.

language: node_js

node_js:
  - 10
  - 9
  - 8

notifications:
  email: false

cache:
  directories:
    - ~/.npm

script:
  - npm run build -- --noEmit # test typescript
  - npm run test # run test
  - npm run coverage # run coverage

branches:
  only:
    - master
    - dev
    - /^greenkeeper.*$/

jobs:
  include:
    # stage will be executed only if the tests are successful
    - stage: greenkeeper
      if: branch =~ /^greenkeeper.*$/ # test if branch its greenkeeper's branch
      script: 
        - npm install -g greenkeeper-lockfile
        - # do lockfile update & upload
    - stage: deploy
      if: branch = master # only deploy the code that is on master
      script:
        - npm run build # build TS
        - npm run release # run release process

I hope some of you can enlighten me.

Thank you for your work with greenkeeper ❤️

I'd assume something like

- stage: greenkeeper
      if: branch =~ /^greenkeeper.*$/ # only run if in a greenkeeper branch
      before_install: npm i -g greenkeeper-lockfile
      install: npm i # always run full install for greenkeeper
      script:
        - greenkeeper-lockfile-update
        - greenkeeper-lockfile-upload

would work, however I've not had a chance to see it work or fail. Also nicely solves the npm ci problem.

Edit: you will also have to force npm i in all other steps, though.

Thanks for your comment ! I don't want to risk breaking my deployment workflow. I'd like someone else's opinion if possible ^^.
