devserver: stage images using image archive uploaded to Google Storage
This adds a devserver feature that'll download an stage individual
images from the builders' Google Storage archive
(gs://chromeos-image-archive).
- Defines a new CherryPy URL (stage_images) and hooks it to the staging
code.
- Implements a downloader for the image archive zipfile (image.zip),
which will fetch it to a temporary directory and unzip the desired
images to the target (staging) directory.
- Uses a flag file for recording the set of images that have already
been staged for a given build.
BUG=chromium-os:33762
TEST=devserver stages requested image files, which can be served in
subsequent requests.
