[runtime tests] Enhance java runtime test.

- Added a bunch of helpful options which help in speeding up the test and
  providing useful output.
- Unexcluded passing tests and updated bugs. Excluded tests which were failing.
- Increased the batch size for java tests so that we can take advantage of
  the shared JVMs.

The running time of the tests decreased from 3+ hours (I don't know the exact
running time because this test has always timed out after 3 hours) to 1 hour
15 minutes. We can reliably run this a CI kokoro job.
