Reevaluate metrics and alerts exposed by the operator

[akrejcir]

Let's reevaluate if the metrics and alerts exposed by the operator and template-validator are useful.

We have these metrics:

• kubevirt_ssp_operator_reconcile_succeeded
• kubevirt_ssp_vm_rbd_block_volume_without_rxbounce
• kubevirt_ssp_common_templates_restored_total
• kubevirt_ssp_template_validator_rejected_total

And these alerts:

• SSPDown
• SSPTemplateValidatorDown
• SSPFailingToReconcile
• SSPHighRateRejectedVms
• SSPCommonTemplatesModificationReverted
• VMStorageClassWarning

@machadovilaca , some time ago, we were wondering if all the alerts and metrics in SSP are useful.
Do you know if some of these can be removed? Or do we have some place describing the usefulness?

I'm unsure where to start investigation.
