garden-o-matic shouldn't depend on test-results.appspot.com
https://bugs.webkit.org/show_bug.cgi?id=69019

Reviewed by Dimitri Glazkov.

This patch moves garden-o-matic from getting full_results.json from
test-results.appspot.com to getting that information directly from the
buildbot.  This patch improve the load time and accuracy of
garden-o-matic because test-results.appspot.com is slow and is dropping
a significant number of writes (see
https://bugs.webkit.org/show_bug.cgi?id=68748).
