"""A library used to set up the system boto.cfg file.
If a project ID is not provided, this request the project ID from the
metadata server and install the compute authentication plugin.
Note the config starts with the content in /etc/boto.cfg.template,
overrides settings, and then persists it into /etc/boto.cfg. This
is done so that the system boto.cfg can be removed prior to image
packaging.
