Dave Grochowski af4d861516 feat(chart): add relay pod extension points (#3322)
## Why
Allow operators to install wrapper binaries and override the relay
entrypoint without maintaining a duplicated Deployment outside the OSS
chart. `extraManifests` can create independent resources but cannot
extend the chart-managed relay Pod.

## What
- Add opt-in init-container, volume, volume-mount, command, and args
extension points
- Preserve image defaults when extensions are empty and compose generic
init containers with the MinIO readiness gate
- Document the distinction from `extraManifests`, add schema coverage,
and release chart 0.1.7

## Risk Assessment
Low — all new values are opt-in, and default rendered manifests are
unchanged apart from version-derived metadata. Merge publishes a new
chart version without modifying existing installations.

## References
- [OpenTelemetry Collector Pod
extensions](https://github.com/open-telemetry/opentelemetry-helm-charts/blob/main/charts/opentelemetry-collector/templates/_pod.tpl)
alongside
[extraManifests](https://github.com/open-telemetry/opentelemetry-helm-charts/blob/main/charts/opentelemetry-collector/templates/extraManifests.yaml)
- [Argo CD
extraObjects](https://github.com/argoproj/argo-helm/blob/main/charts/argo-cd/templates/extra-manifests.yaml)
alongside component-scoped Pod extension hooks
- `helm unittest` 0.8.2: 43/43 tests passed
- Helm lint, schema validation, fixture renders, and chart packaging
passed
- Oracle review found no functional issues; its literal no-`tpl`
regression test recommendation is included
