Subject: [PATCH] feat: configurable common path prefix for values files (#408)

Removes duplicated declaration path for cleaner helmfile, for example, this configuration.

```
- chart: projectABC
  name: {{ .Environment.Name }}-projectABC
  namespace: abc
  version: {{ .Environment.Values.projectABC.chart.version }}
  valuesPathPrefix: ../values/{{ .Environment.Name }}/
  values:
  - common.yaml
  - project-abc.yaml
  - platform.yaml
  - ...
  secrets:
  - secrets.yaml
```
