* Add PVC source support for DataImportCron
A PVC from any namespace can now be the source for a DataImportCron. The
source digest is based on the PVC UID, which is polled by the schedule
similarly to image stream, so when a new PVC is detected it will be
imported.

Add DataVolume not-Running condition reason ImagePullFailedReason for
DataImportCron controller deletion of erroneous DVs.
In [test_id:8266] we exercise this flow by injecting a nonexistent
digest for the registry import, which did not lead us to the
ImagePullFailed flow but the usual GenericError one, as the container
status got the InvalidImageName reason because the digest was not 64
long. Fixed that.
Added InvalidImageName reason as a trigger of ImagePullFailed as
well.

---------

When the DataImportCron last import DV is manually deleted, the
controller reconciles, but due to k8s default background cascading
deletion, the PVC may still temporarily exist, so the controller will
not re-create the DV even after the PVC is deleted, unless it reconciles
due to other watched CR like DataSource. In the scenario of CNV-39688,
since we move from pvc source format to snapshot, the DataSource won’t
update until a snapshot is created, which will never happen. To solve it
we add a watch for deletion of DataImportCron-labeled PVCs. The change
was tested locally, but since it required two storage classes it’s
currently out of scope for the existing CI lanes, so it requires tier-2
test.

This change caused a unit test to be flaky:
https://github.com/kubevirt/containerized-data-importer/pull/3176/files#
Before, this code would round down to the second, and add 1. Essentially
doing a "ceil" on the time delta.
After the change, the round-down part disappeared, so it became a plain
+1 rather than a ceil.
The unit test in question has an assertion ensuring that this value is
within 0 and 60.
If this value is within 59 and 60:
- Before #3176: rounds up to 60 (test passes)
- After #3176: is mapped to within 60 and 61 (test fails)
I didn't want to revert to the old code because it was a bit confusing,
so I removed the +1, which I understand it's there to make sure we
don't undershoot (no longer necessary as we don't round down anymore).

an error event and the PVC will be Pending for the default SC, so when
there are such Pending PVCs we will fire an alert.

SC does not support CSI/Snapshot clone (smart clone) or does not have

* 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.

A recent design proposal within the KubeVirt community introduced the
idea of inferring the details of default instance type and preferences
from a given volume associated with a VirtualMachine [1]. The idea being
to further reduce the number of choices a user has to make to get a
bootable VirtualMachine to a single choice of a PVC.
This change aims to support this effort by allowing operators to
annotate the underlying DataVolumes, DataSources and PVCs at import time
through CDI by first annotating the initial DataImportCrons.
This is useful to users of CDI such as the KubeVirt SSP operator that
currently defines a number of DataImportCrons to pull in various boot
sources required by the KubeVirt common-templates project.
Both the DataVolume and DataSource associated with the DataImportCron
are annotated to allow KubeVirt to potentially avoid a deeper lookup of
the associated PVC when attempting to infer these defaults.
