Fixes LP Bug #827660 - Swift driver fails to upload image files greater than 5GB. The swift store driver was not using the large object manifest methods required to upload objects greater than 5GB into Swift. Adds configuration options to specify the size in MB that an image file should be considered for large object manifest, and a configurable chunk size. We use a disk buffer of this size, adding chunks of the image file into Swift and then after all chunks are saved, add the manifest to Swift. Change-Id: I4b4421aa1bba584ab242016a041e864ef19d0214

Glance
======
Glance is a project that defines services for discovering, registering,
retrieving and storing virtual machine images. The discovery and registration
responsibilities are handled by the `glance-registry` component while the
retrieval and storage responsiblities are handled by the `glance-api`
component.
Quick Start
-----------
If you'd like to run trunk, you can clone the git repo:
git clone git@github.com:openstack/glance.git
Install Glance by running::
python setup.py build
sudo python setup.py install
By default, `glance-registry` will use a SQLite database. If you'd like to use
MySQL, or make other adjustments, you can modify the glance.cnf file (see
documentation for more details).
Now that Glance is installed, you can start the service. The easiest way to
do that is by using the `glance-control` utility which runs both the
`glance-api` and `glance-registry` services::
glance-control all start
Once both services are running, you can now use the `glance-upload` tool to
register new images in Glance.
glance-upload --type=machine --kernel=1 --ramdisk=2 myimage.img "MyImage"
With an image registered, you can now configure your IAAS provider to use
Glance as its image service and begin spinning up instances from your
newly registered images.
