One of the mandates of the [webpack working group](https://about.gitlab.com/company/team/structure/working-groups/webpack/) is to improve (reduce) the memory requirements of the GDK. Before we can make any progress in this area, we should have a reliable way to measure our progress. We should create a CICD job (either in gitlab-ce or gitlab-development-kit) which will measure this for us by running the `webpack-dev-server` process and measuring its memory consumption once it is in its "ready" state.
