Creating cluster with 'volumeSpec' does not include default storageClass

[kalium99]

Not sure if this is a bug or expected behaviour (perhaps the latter), but I copied the example in the docs for the optional volumeSpec, modifying only the value for storage:

volumeSpec:
    accessModes: [ "ReadWriteOnce" ]
    resources:
      requests:
        storage: 20Gi

This fails though due to having no storageClassName (which took me a few minutes to work out). I guess I should have known better, but maybe even mentioning storageClassName in the example docs may help (or even adding adding default storageClassName if none is present?).

We expect that the cluster has a default storage class configured. If that's not the case, you can specify the storageClassName inline.

We add some documentation about this in #215

As @calind said the operator expects that the default storage class is configured, otherwise you should specify the storageClassName.
