I first tried to setup an app_engine standard env app and import the chromite lib. It turned out the importing third-party libraries and setting up virtualenv could be messy in standard evn. Then I tried the flexible env, which is good for flexible vendor setup but not good for easy scaling, importing chromite works smoothly so far. Flexible env will make maintaining for chromite easier than the standard evn and offers more flexible env setup (like virtualenv), so proceeding with flexible env is the plan.

cidb: Add extra request_reasons to buildRequestTable.

Previously, the requested CQ slaves and their buildbucket_ids were only
stored in in-memeory metadata and uploaded to GS. The project
CrOs-CL-Status-Viewer needs to access the CQ master in history and its
scheduled CQ slaves. Plan to store the information in the
buildRequestTable so CL-Status-Viewer can know the scheduled slaves and
their buildbucket_ids even the scheduled slaves never started or failed
before the BuildStart stage (which inserts the build tuple into the
buildTable).

also access the information

3) sync_stages: change Pre-CQ-Launcher to use InsertBuildRequests.

chromite changes for Cros_CL_Status_Viewer

1) cidb.GetBuildStatus should return the build_type of a build.
CQs/Pre-CQs can be deleted from chromeos_configs, so
Cros_CL_Status_Viewer won't be able to know the build_type of the builds
it collects for a CL if the build configs have been removed;
2) buildbucket request should also include the build_type in the tag.
also add GetBuildTags API in buildbucket_lib.
3) add GetBuildRequestsForRequesterBuild so that Cros_CL_Status_Viewer
can know the scheduled slaves (including the slaves failed to start
Cbuildbot) given a master build id.

cl_status_server: Get status and build information for a CL.

CLStatusServer gets and computes status and relevant Pre-CQ & CQ
builds given a CL (gerrit_host + change_number + patch_number).

CLStatusServer gets CL status by analyzing CLActions from CIDB.
CLStatusServer gets build information from CIDB if the build has
already started and reported status to CIDB, and gets build information
from Buildbucket if the build has been scheduled but hasn't reported
information back to CIDB.
