When developers run tests on their PRs, we want developers to be able to execute tests with ease. To this end, we want to establish a test marker so that developers can run a simple IQE command like the following:

ENV_FOR_DYNACONF=ephemeral NAMESPACE=$NAMESPACE iqe tests plugin platform_ui -m <developer_marker> 

We can call the marker whatever we like, we just have to be consistent with how we apply it to our tests. Ideally, the test set should be minimal. Approximately 5-10 tests that are expected to always work within the ephemeral environment assuming the UI is deployed.
