For the upcoming replacement for webkit-test-results.appspot.com, new-run-webkit-tests needs to use a new JSON format
that contains the full summary of the test run including information about passed tests.

Add this ability to NRWT so that I can start testing this feature. This patch adds the following optoins to NRWT:
--build-slave
--got-revision
--results-server-host

The last option is somewhat ambigious with --test-results-server but we're intending to deprecate the old server
so we should be able to delete --test-results-server in time.
