Add kubebuilder:printcolumn directives to generated resources

[babbageclunk]

Describe the current behavior
At the moment generated resources don't indicate their provisioning state in tabular kubectl output, so you need to keep checking the yaml output to find out whether they're ready.

Describe the improvement
Adding kubebuilder:printcolumn comments to the generated code would make them much nicer to use:

// +kubebuilder:printcolumn:name="ProvisioningState",type="string",JSONPath=".status.provisioningState"

(Although the name ProvisioningState's probably a bit long.)

At the moment there's not really an equivalent of the message field on the ASOv1 resources - once the condition work spec'd in #1614 is done it would make sense to use the status and message fields from the ready condition (presumably these will supplant the status.provisioningState).
