* Get rid of unnecessary DIC reconcile updates
Also fixed status.lastExecutionTimestamp to be the last polling time
as intended in the design, and not the last reconcile update time.

Watch UpdateFunc predicate is checking if ObjectNew has DataImportCron
label with value, while the request enqueue mapping function may refer
the old object before the label value was set, resulting it to pass a
reconcile.Request where Name is an empty string.

* Delete erroneous DV on DIC desired digest update
When a DataImportCron import DV is condition Running=False with
Reason=Error it indicates this DIC might get stuck with this DV forever,
so no new import DVs will be created even if the source sha256 is
updated. With this change, when digest is updated, before creating the
new DV, we simply delete the erroneous DV if necessary.
Also includes some DataImportCron tests improvements and cleanup.

The following labels should be set by the operator that creates the
resource, and not by the DataImportCron controller, otherwise it may

* Remove tag from DataImportCron registry source URL
There are cases when DataImportCron registry source URL contains tag
referring a specific version. We use this tagged URL when polling for
source updates, but on import we would like to remove the tag as we use
a specific sha256. E.g. for docker://quay.io/containerdisks/centos:8.4
the :8.4 tag will be removed.

* Add DataImportCron status conditions
The `DataImportCron` controller updates the status conditions in a
controlled `DataImportCron` and its managed `DataSource`.
DataImportCron:
- UpToDate - indicates if the the most recent import is successful and
`DataSource` is up-to-date. Updated to False whenever the source
digest (latest sha256) is updated.
- Progressing - indicates whether the cron is currently in the process
of importing. Updated to True if there is a current import and its
`DataVolume` is `ImportInProgress`, otherwise False.
DataSource:
- Ready - indicates that the corresponding pvc exists and is populated.
Update according to `DataImportCron.Status.LastImportedPVC`
`DataVolume`'s `DataVolumeReady` condition, if the `DataVolume`
exists. Otherwise False. Unlike `DataImportCron` `UpToDate`
condition, this one does not care about newer source digest.

* Add DataImportCron controller
-The new controller polls for updates to a registry source container
image, based on a given schedule. When updates to a container image are
detected, the controller imports the content into a new uniquely named
PVC in a golden image namespace.
-For each DataImportCron, the controller manages a corresponding
DataSource to always point to the latest most up-to-date golden
image PVC.
-DataImportCron takes ownership of an existing DataSource (with
controller: false), allowing an admin to opt-in to using auto
delivery/updates later on.
-The controller has PVC garbage collector removing old PVCs.

-status conditions updates

- isolate imagestream and registry specific code
- fix namespace of CronJob, and its job and pod to CDI namespace
- manage CronJob-DataImportCron ownership relationship with a finalizer,
handle DataImportCron deletion (CronJob etc.)
- remove CronJob and job pod for ImageStreams, use RequeueAfter and
cronexpr instead
- add k8s app cdi-source-update-poller executed by CronJob to poll source
image digest via skopeo inspect for url registry source, and annotate
the DataImportCron when the image was updated and pending for import based
on the cron schedule
- add cdi-source-update-poller and skopeo binary to the cdi-importer container
