adding frozen-lockfile?

[compojoom]

Feature Request

I think that we should install yarn dependencies with --frozen-lockfile:
https://circleci.com/docs/2.0/yarn/
https://stackoverflow.com/questions/52630404/how-to-install-packages-based-on-the-lock-file-with-yarn
https://yarnpkg.com/lang/en/docs/cli/install/

If you need reproducible dependencies, which is usually the case with the continuous integration systems, you should pass --frozen-lockfile flag.

Any objections?
