Option to keep mongodb PVC

[bumpow]

Provide the option through helm values to keep the mongodb PVC after uninstalling the chart to avoid losing the bind to the corresponding PV with hyperdx's state.

I thought I could create a PR to contribute directly but it looks like I'm not allowed to push to a new branch. However, the changes are simple enough that I can just paste them here.

charts/hdx-oss-v2/values.yaml

  mongodb:
    ...
    persistence:
      enabled: true
      dataSize: 10Gi
+     keepPVC: true
    livenessProbe:
      enabled: true
      initialDelaySeconds: 10

charts/hdx-oss-v2/templates/claims/persistent-volume-claims.yaml

    name: {{ include "hdx-oss.fullname" . }}-mongodb
    labels:
      {{- include "hdx-oss.labels" . | nindent 4 }}
+   {{- if .Values.mongodb.persistence.keepPVC }}
+   annotations:
+     helm.sh/resource-policy: keep
+   {{- end }}
  spec:
    accessModes:
      - ReadWriteOnce
