  1. WORKER monitors the status of pull requests in GITHUB repos by Github API
  2. WORKER monitors the status of TRYBOT by the JSON API provided by http://wrt-buildbot.bj.intel.com/buildbot/json/help
  3. run_trybot_github.sh is a wrap script to run depot_tools/trychange.py to create the build in trybot.
  4. The dashboard in GITHUB repo actually is a comment sent by the WORKDER, which can be updated by reviewers and WORKER.
  5. Reviewers can select the bots they want to try.
  6. Reviewers can select the bots to rebuild the patches.
