Chart versions for applications installed by one click install buttons should be version locked
We should make sure that we lock the version so that they don't follow the latest version in the repo.
Depending on the latest chart version is very risky and means that our production system can break without us making any changes. It also means that it won't get picked up by our CI and we may be forced to patch production if this happen which is a very time consuming process.
We've fixed this already for Prometheus here https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20010
