Changed SetValue.Values type from []string to []any to allow passing
maps (not just strings) in the values field of set/setTemplate.
Previously, YAML like:
setTemplate:
- name: source.helm.parameters
values:
- name: demo
- version: v2
would fail with 'cannot unmarshal !!map into string'. Map values are
now serialized to JSON when generating --set flags.
Fixes#1021
