* Suppress alerts to reduce noise of dependent ones
This is a follow-up to #2998 introducing the following changes to alert
rules:
- CDIDefaultStorageClassDegraded - do not fire when no default SC
(either k8s or virt).
- CDIDataImportCronOutdated - do not fire when no default SC (either
k8s or virt), as DIC import DVs use default SC.
- CDINoDefaultStorageClass - fire not only when there is a pending DV
(and PVC) but also when DV has an empty status (waiting for default
SC etc.)

* Add Prometheus alerts and label existing alerts
- CDINoDefaultStorageClass - not having a default (or virt default)
SC is surely not an OpenShift error, as admins may prefer their cluster
users to only use explicit SC names. However, in the CDI context when
DV is created with default SC but default does not exist, we will fire
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.
- CDIDefaultStorageClassDegraded - when the default (or virt default)
SC does not support CSI/Snapshot clone (smart clone) or does not have
ReadWriteMany access mode (for live migration).
- CDIStorageProfilesIncomplete - add storageClass and provisioner
labels.
- CDIDataImportCronOutdated - add dataImportCron namespace and name
labels.

* Add label explanation to new metric help
Also rename the metric kubevirt_cdi_storageprofile_status to
kubevirt_cdi_storageprofile_info since it always reports value 1,
where the label values provide the details about the storage
class and storage profile.

* Add alert for DataImportCron failing
DataImportCrons now have conditions (particularly UpToDate) that tell us if
things are going as planned. We can utilize those to alert whenever were not UpToDate for a while.

* 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.
