Enable dynamically provisioned persistent volumes

[wallrj]

Minikube has a storage-provisioner addon which should allow it to dynamically provision hostpath volumes.

It might be useful / simpler to be able to test Navigator databases with dynamically provisioned volumes.
Right now we have to create PVs manually.

I note that there appear to be some bugs in the hostpath provisioner which may prevent it working with Databases that run as non-root user:

• Directories provisioned by hostPath provisioner are only writeable by root kubernetes/minikube#1990
