It doesn't make sense to have two classes of flaky tests. While it may take the constrained environment of CI to trigger failures easily it doesn't mean they don't occasionally happen on developer machines. As CI is the gating factor to passing there is no point developers running the tests locally anyway unless they are trying to fix things. While we are at it update the language in the docs to discourage the QEMU_TEST_FLAKY_TESTS becoming a permanent solution.
