cros-bisector: ansible: use service account for git auth
Changes in this CL:
- use credential provided in gcloud instead for git auth
- cipd auth issue
- minor fixes
The current git auth flow is provided by git-cookie-authdaemon, this
daemon will initialize auth by gce IAM and update token every 10 mins.
The cipd auth issue is mentioned in b:149077936, a fesible solution now
is run gclient through luci context, may need to discover more graceful
solution in the future.
