Title: Parameterize the Chef role names used in recipes

Both the Glance API and Registry recipes were hard-coding
the names of the Chef roles that the recipes -- via the
osops-utils::ip_location::get_settings_by_role call --
were depending on.

This patch parameterizes those hard-coded Chef role
names, allowing deployers who have their roles named
differently, to use these cookbooks.
