Add simplest happy path end-to-end test of Monitor feature
Summary
As a first pass at adding more integration tests for Monitor features, we want to build out one, simple end-to-end test. The larger issue is https://gitlab.com/gitlab-org/gitlab-ce/issues/58407
Improvements
We need to:
- Identify the easiest happy path to test
- Talk to Mek and/or Dylan about what already exists in the QA test suite and how we should expand on it.
- Deliver one test to the QA test suite that exercises on of our features. This does not necessarily need to be a Debugging & Health feature. It could be APM.
