dev: Let devserver use gsutil functions in chromite.
Together with CL:378576, this CL is to make platform/dev to use GS-related
functions in chromite. This could help reduce the maintain cost and
inconsistency errors caused by different versions of gsutil.
BUG=chromium:640609
TEST=Ran unittest.
Test 2 functions with local devserver: trigger_download &
get_latest_build_in_gs (including xbuddy/latest, xbuddy/latest-official,
xbuddy/latest-{dev|beta|stable}, xbuddy/latest-R53).
