Allow for custom volumeClaimTemplates in the statefulset #51
Description
Is your feature request related to a problem? Please describe.
I would like cache the acme tls library directory but still allow for high availability. Currently my storage provider longhorn is buggy for me with a NFS ReadWriteMany volume and i would move to a RWO pvc for each pod.
Describe the solution you'd like
An additional volumeClaimTemplate value in the server section that will be merged with the existing hard coded values https://github.com/openbao/openbao-helm/blob/82f042c3075a0c65097111f110955ec2d86f5c25/charts/openbao/templates/_helpers.tpl#L283C1-L322C12
Describe alternatives you've considered
A RWX volume would probably be ok but i'd love to just not use it.
