feat(cluster): add pvcTemplate to storage config

[davideperozzi]

Added the option "pvcTemplate" to cluster.storage and cluster.walStorage. Added some documentation and references to the documentation

[cfis]

Any chance we could push this forward? I need this functionality also.

@cfis I think the only thing missing are the tests. I don't really know how they work in Helm and currently don't have the time to look into it, but if someone has the time to figure it out. I suppose it just tests against the installed manifest on the cluster?

[cfis]

You can test the outputted helm files...is that is what is needed?

I just tested this feature but can't figure out to make it working... Here is the values.yml storage part:

    pvcTemplate:
      accessModes:
        - ReadWriteMany
      resources:
        requests:
          storage: 20Gi
      storageClassName: local-storage
      volumeMode: Filesystem

Result in a pvc:

spec:
    accessModes:
    - ReadWriteOnce
    resources:
      requests:
        storage: 8Gi
    volumeMode: Filesystem

What's interesting here is that the helm get values return the right template....
