Could someone kindly explain how a service like Glance verifies a token against Keystone? I am looking for the code

As far as I know, all services use the keystoneauth library, though the auth mechanism can be configured in their paste files such as glance-api-paste.ini.
In the case of Glance, the flavor config parameter in glance-api.conf selects one of the pipelines in glance-api-paste.ini, by default glance-api-keystone.
