As we have more tests in VMTest, we can spot more problems in pre-CQ without breaking CQ. Let us add more tests to VMTest.

We need to care several points:
1. VMTest should not depend on hardware futures. For example: no graphics tests.
2. VMTest runs sequentially, so we should prefer quick tests.
3. VMTest runs very frequently, so we should prefer non-flaky tests.
4. VMTest runs for every CL, so we should prefer tests that efficiently catch bad CLs (in other words, most frequently failing tests)
