Add stage name in job.json response

Closes #52618

See merge request gitlab-org/gitlab-ce!22317

The function that was checking if the job was started or not
was expecting a boolean, however it was receiving a null.
During the refactor the condition was changed, causing the function
to break with null

This commit fixes the check

This adds a method to Gitlab::GonHelper called
`push_frontend_feature_flag`. This method can be used to easily expose
the state of a feature flag to Javascript code. For example, using this
method we may write the following controller code:

    before_action do
      push_frontend_feature_flag(:vim_bindings)
    end

    def index
      # ...
    end

    def edit
      # ...
    end

In Javascript we can then check the state of the flag as follows:

    if ( gon.features.vimBindings ) {
      // ...
    }
