# this function returns the endpoint uri for a service, it takes an tuple
# input in the form: service-type, endpoint-class, port-name. eg:
# { tuple "orchestration" "public" "api" . | include "helm-toolkit.keystone_endpoint_uri_lookup" }
# will return the appropriate URI. Once merged this should phase out the above.
