For consistency with the standard openstack CLIs, we use the same set of config/command line/env var options to provide credentials for the glance pollster's interaction with the glance-registry. (The exception here is the ability to pass in a previously acquired authentication token via --os-auth-token/OS_AUTH_TOKEN, as this would not make sense for a long-lived service given the limited lifetime of keystone tokens.) As well as having the advantage of familiarity, this approach allows users to avoid encoding sensitive credentials in config files (instead environment variables or command line options may be used). Also, if future non-glance pollsters need authenticated access to other openstack services, more generic naming of the config options would be preferable.
