Tests: Only set ginkgo focus in kind tests (stolostron#1461)

Previously, we tried to cleverly decide which tests to run on PRs.
However this is error prone, and has recently allowed code to be checked
in which broke a test for almost 4 months. This due the said test not
being included in any of the Ginkgo focus tags selected.

While this will use more resources, it's less error prone, and we ensure
we cannot checkin code that breaks tests.
