1. [release-v1.58] Add new Prometheus alerts and label existing alerts …

   Manual backport of kubevirt#2998 & kubevirt#3038
   
   - 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.
   
   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 snapshot manifests for tests and deploy snapshot CRDs in the hpp
   destructive lane
