Support expansion of PVCs

[WolfspiritM]

Hi,

Currently StatefulSets don't support the change of volumeClaimTemplates after creating.
This is (especially for a database) a bad thing cause if the storage increases it is hard to increase the volume size.

kubernetes/kubernetes#68737
kubernetes/enhancements#660
kubernetes/enhancements#661
kubernetes/enhancements#1848

It would be nice if the operator can detect changes to the volumeClaimTemplates and patch the existing PVCs accordingly as a workaround.

hi @WolfspiritM

Thanks for the question and the links provided.

The process of handling resizing is quite complicated, we have a description of how it can be done manually for the enterprise Operator here: https://docs.mongodb.com/kubernetes-operator/stable/tutorial/resize-pv-storage/ and it can be applied to the community operator as well. I think so far the support for the automatic resizing done by the Operator is not planned in the near future but we always welcome any help!
