[opentelemetry-collector] HPA not finding StatefulSet

[lindeskar]

The autoscaling of StatefulSets introduced in #1011 is not working.

Warning in HPA events:

the HPA controller was unable to get the target''s current scale:
no matches for kind "Statefulset" in group "apps"

Probably caused by the capitalization from:

opentelemetry-helm-charts/charts/opentelemetry-collector/templates/hpa.yaml

Line 12 in 694104b

kind: {{ title .Values.mode }}

Which renders to:

kind: Statefulset

When I manually change it to:

kind: StatefulSet

everything works fine.
