# This function helps resolve database style endpoints:
#
# Presuming that .Values contains an endpoint: definition for 'neutron-db' with the
# appropriate attributes, a call such as:
# { tuple "neutron-db" "internal" "userClass" "portName" . | include "helm-toolkit.endpoints.authenticated_endpoint_uri_lookup" }
# where portName is optional if a default port has been defined in .Values
# returns: mysql+pymysql://username:password@internal_host:3306/dbname
