Result Flow implementations.

This binary's subcommands transform the ChromeOS Test Platform implementation output to Skylab test results in a user friendly format and insert them into Bigquery.

Result Flow has below subcommands for different Recipes:

publish

Executed twice in cros_test_platform Recipe, publish pushes a CTP build ID to Pub/Sub:

• before test execution: notify the subscriber that a new CTP build was kicked off, and its metadata is ready.
• after test execution: notify the subscriber to update CTP build's status.

ctp

Run in Result Flow Recipe, ctp pulls a set of CTP Build IDs from the Pub/Sub topic. By calling Buildbucket API, ctp catches the CTP's metadata and status(whether the build is completed), transforms to test_platform/analyticsTestPlanRun and uploads to Bigquery.

skylab

Run in Result Flow Recipe, skylab catches the test runner build ID from the Test Runner Pub/Sub topic. Via Buildbucket's GetBuild call, it collects the test runner output, transforms it into test_platform/analytics/[TestRun|TestCaseResult], and inserts to Bigquery.
