Tool to bulk-enable tests that are now passing on Ravenwood.

Currently only offers to include classes which are fully passing; ignores
classes that have partial success.

Typical usage:
$ RAVENWOOD_RUN_DISABLED_TESTS=1 atest MyTestsRavenwood
$ cd /path/to/tests/root
$ python bulk_enable.py /path/to/atest/output/host_log.txt
