I have the PVC assembly part of the PR completed and I am now working on
wiring all this up to make sure it works correctly with custom Pod Templates.
Commands:
```bash
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.claimName=nameOfVolumeClaim
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.storageClassName=storageClassNameOfChoice
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.accessModes=comma,separated,list
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.sizeLimit=555Gi
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.volumeMode=volumeModeOfChoice
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.path=path/to/mount
--config-property
heron.kubernetes.volumes.persistentVolumeClaim.volumeNameOfChoice.subPath=sub/path/to/mount
```
Will generate the PVC:
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: nameOfVolumeClaim
spec:
volumeName: volumeNameOfChoice
accessModes:
- comma
- separated
- list
volumeMode: volumeModeOfChoice
resources:
requests:
storage: 555Gi
storageClassName: storageClassNameOfChoice
```
Entries will be made in the Pod for a `Volume` and in the `executor`
container for the `VolumeMount` with the `path` as well as the `subPath`, as
required.
The commands above are all that I have added for now but the code is
designed so that you can easily add an enum for the PVC property. You would
then need to add an entry to the switch statement which adds it to the actual
PVC. This should make things more maintainable and significantly more
extensible.
