# This function returns the scheme for a service, it takes an tuple
# input in the form: service-type, endpoint-class, port-name. eg:
# { tuple "etcd" "internal" "client" . | include "helm-toolkit.endpoints.keystone_scheme_lookup" }
# will return the scheme setting for this particular endpoint.  In other words, for most endpoints
# it will return either 'http' or 'https'
