* Disable DV GC by default
DataVolume garbage collection is a nice feature, but unfortunately it
violates fundamental principle of Kubernetes. CR should not be
auto-deleted when it completes its role (Job with TTLSecondsAfter-
Finished is an exception), and once CR was created we can assume it is
there until explicitly deleted. In addition, CR should keep idempotency,
so the same CR manifest can be applied multiple times, as long as it is
a valid update (e.g. DataVolume validation webhook does not allow
updating the spec).
When GC is enabled, some systems (e.g GitOps / ArgoCD) may require a
workaround (DV annotation deleteAfterCompletion = "false") to prevent
GC and function correctly.
On the next kubevirt-bot Bump kubevirtci PR (with bump-cdi), it will
fail on all kubevirtci lanes with tests referring DVs, as the tests
IsDataVolumeGC() looks at CDIConfig Spec.DataVolumeTTLSeconds and
assumes default is enabled. This should be fixed there.

* move cleanup out of dv deletion
It seemed off to call cleanup in the prepare function
just because we don't call cleanup unless the dv is deleting.
Instead we check in the clenup function itself if it should be
done: in this 2 specific cases in case of deletion and in case
the dv succeeded.
The cleanup will be used in future commit also for population cleanup
which we also want to happen not only on deletion.

The populators are handling existing PVCs.
The PVC already has a defined requested size,

Instead if the populators is using by PVC that the
datavolume controller created the inflation will happen
there if needed.

* Create PVC if possible even if SC is missing
When PVC is created with storageClassName and the SC is not found,
k8s looks for PV with the storageClassName for satisfying this claim.
In this case k8s supports also a blank (“”, not the nil default one)
storageClassName. To support this behavior we added:
-DV controller support for this flow (for both “” and non-existing SC)
-Condition update and event when StorageSpec PVC rendering errors and
PVC is not created (e.g. missing both AccessModes and SC/PV)
-PVC is created even if a satisfying SC/PV doesn't exist if pvc/storage
AccessModes is set (otherwise k8s PVC validation fails). PVC/DV phase
will be Pending until a satisfying SC/PV is found
-PV watch to reconcile DVs waiting for the PV storageClassName
-PV storageClassName indexer, so we can list the relevant PVs

The import populator is a controller that handles the import of data in PVCs without the need of DataVolumes while still taking advantage of the import-controller flow.

* Add support for volume populators in CDI
This commit enables the use of volume populators in CDI, so datavolume-owned PVCs can be populated using custom logic.
Volume populators are CRDs used to populate volumes externally, independently of CDI. These CRDs can now be specified using the new DataSourceRef API field in the DataVolume spec.
When a DataVolume is created with a populated DataSourceRef field, the datavolume-controller creates the corresponding PVC accordingly but skips all the population-related steps. Once the PVC is bound, the DV phase changes to succeeded.

* dataimportcron: Pass KubeVirt instance type labels to DataVolume and DataSource
Following on from 4fbcb2d509 a requirement
has arisen to expose the default instance type metadata previously
exposed as annotations also as labels to allow callers such as the UI to
have simple server side filtering of these resources.
The unreleased feature implementation in KubeVirt has now
switched to labels and so CDI should now do the same and pass through
the appropriate labels to the underlying resources.
Signed-off-by: Lee Yarwood <lyarwood@redhat.com>
* instancetype: Pass instance type labels from DataVolume to PVC
Unlike annotations not all labels are copied from a given DataVolume to
a PVC during an import. This change corrects this for instance type
labels ensuring they are passed down to the underlying PVC.
The associated constants are also moved into pkg/controller/common/util
to allow access from the DataImportCron and DataVolume controllers.
