+ Perf dashboard erroneously shows an old OS build in A/B testing range
+ https://bugs.webkit.org/show_bug.cgi?id=149942
+
+ Reviewed by Darin Adler.
+
+ Ordering OS builds lexicologically turned out be a bad idea since 15A25 falls between 15A242 and 15A251.
+ Use a fake/synthetic timestamp to force the commonly understood total order instead.
+
+ Refactored pull-os-versions.py to share the server config JSON with other scripts. Also made the script
+ support pulling multiple sources; e.g. both OS X and iOS.
+
+ Also removed superfluous feature to submit results in chunks. The perf dashboard can handle thousands of
+ revisions being submitted at once just fine.
+
+ * public/api/commits.php:
+ (main): A partial revert of r185574 since we no longer need to order builds lexicologically.
+
+ * tools/pull-os-versions.py:
+ (main): Takes --os-config-json, --server-config-json, and --seconds-to-sleep as arguments instead of
+ a single --config argument to share the server config JSON with other scripts.
+ (OSBuildFetcher): Extracted out of main. This class is instantiated for each OS kind (e.g. OS X).
+ (OSBuildFetcher.__init__): Added.
+ (OSBuildFetcher._fetch_available_builds): Extracted out of main. Fetches available builds from a website
+ or custom commands.
+ (OSBuildFetcher.fetch_and_report_new_builds): Extracted out of main. Submits the fetched builds after
+ filtering out the ones we've already reported.
+ (OSBuildFetcher._assign_fake_timestamps): Creates a fake timestamp to establish a total order amongst each
+ OS X / iOS style build number such as 12A3456b.
