An earlier change [0] removed the older cinder v1 and v2 endpoint
definitions from values.yaml. If older APIs are required, they can be
enabled using overrides, but the ks-service job only creates a volumev3
endpoint.
This change updates the ks-service job to create all endpoints defined
in .Values.endpoints that have "volume" in their name. Note that several
settings are hardcoded to use volumev3, so this change would mostly
useful in enabling v2 in addition to v3.
