[tempo] Add ability to set `persistentVolumeClaimRetentionPolicy` in Tempo StatefulSet

[aerfio]

Add ability to set persistentVolumeClaimRetentionPolicy like in other charts:

• https://github.com/grafana/helm-charts/blob/83365ca13d40222b636d81b33b2fe703fc970505/charts/loki-distributed/templates/compactor/statefulset-compactor.yaml#L24
• https://github.com/grafana/helm-charts/blob/83365ca13d40222b636d81b33b2fe703fc970505/charts/loki-distributed/templates/index-gateway/statefulset-index-gateway.yaml#L24
• https://github.com/grafana/helm-charts/blob/83365ca13d40222b636d81b33b2fe703fc970505/charts/loki-distributed/templates/ingester/statefulset-ingester.yaml#L29
• Loki repo: https://github.com/grafana/loki/blob/26dfd628f0effe2367420f591da36727ebe78806/production/helm/loki/templates/single-binary/statefulset.yaml#L34

I can also expose the ability to override

    whenDeleted: Delete
    whenScaled: Delete

if requested.

Hey @aerfio sorry for the delay, I'm a bit occupied as of now, but will review it soon!

Hey @aerfio you'd need to bump chart version to 1.14.0 before I could approve this!

@Sheikh-Abubaker done!

@aerfio could you please address the failed CI check by running helm-docs inside /charts/tempo/

@Sheikh-Abubaker re-run helm-docs.
