Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1496755

Use unstructured builder to obtain resources before exporting.
This allows us to support service-catalog resources.

Before

$ oc export serviceinstance/my-service-instance
the provided version "servicecatalog.k8s.io/v1alpha1" has no relevant versions: group servicecatalog.k8s.io has not been registered
no matches for servicecatalog.k8s.io/, Kind=ServiceInstance

After

$ oc export serviceinstance/my-service-instance
apiVersion: servicecatalog.k8s.io/v1alpha1
kind: ServiceInstance
metadata:
  creationTimestamp: ""
  deletionTimestamp: null
  finalizers:
  - kubernetes-incubator/service-catalog
  generation: 1
  name: my-service-instance
  namespace: ""
...

@liggitt this fixes the issue I had mentioned in our conversation earlier.
Exporting unstructured objects with an empty string as the value of their
creationTimestamp field was causing an error [1] when trying to re-create
those objects with oc create.

$ oc export bc/foo > foo.yaml
...
$ oc create -f foo.yaml
Error from server (BadRequest): BuildConfig in version "v1" cannot be handled as a BuildConfig: parsing time "" as "2006-01-02T15:04:05Z07:00": cannot parse "" as "2006"

Will open upstream PR if this looks okay.

Assigning a nil key to the internal map seems to be a perpetuation of the problem outlined in kubernetes/kubernetes#48211 (related to several bugs).

Potentially diverging from upstream by carrying a patch for this particular change seems riskier than usual given the history of nuanced serialization problems in this type. My suggestion would be to make an upstream commit a prerequisite.

@ironcladlou you'll be the likely reviewer upstream. Will it merge upstream?

@juanvallejo, can you extract this patch into an upstream PR and include a unit test demonstrating that it fixes a bug?

I'm ok with the approach, but only if we deprecate oc export and stop adding any new features to it.

@fabianofranz it's a pretty ugly hammer, but it behaves slightly better on unknown types.

@deads2k

@juanvallejo you got a release note ready?

Modified the "export" command to be able to deal with resources not known to the client.
Resources, such as thirdparty-resources and service catalog resources, can now be used with this command.
