wrong values in helm chart template

[masikrus]

Bug report:

$ helm pull dragonfly/dragonfly
$ tar -zxf dragonfly-1.1.33.tgz
$ grep -r Values.metrics ./dragonfly/templates/
./templates/manager/metrics-svc.yaml:{{ toYaml .Values.metrics.service.labels | indent 4 }}
./templates/seed-peer/metrics-svc.yaml:{{ toYaml .Values.metrics.service.labels | indent 4 }}
./templates/seed-client/metrics-svc.yaml:{{ toYaml .Values.metrics.service.labels | indent 4 }}
./templates/trainer/metrics-svc.yaml:{{ toYaml .Values.metrics.service.labels | indent 4 }}
./templates/scheduler/metrics-svc.yaml:{{ toYaml .Values.metrics.service.labels | indent 4 }}

i think should be
.Values.${APPNAME}.metrics.service.labels

fix please
