Description of problem:
kubevirt_vmi_memory_domain_total_bytes, kubevirt_ssp_total_restored_common_templates, kubevirt_vmi_filesystem_total_bytes don't follow the
naming conventions as the other metrics.

"total" should be at the end of the metric name
kubevirt_vmi_memory_domain_total_bytes -> kubevirt_vmi_memory_domain_bytes_total
kubevirt_ssp_total_restored_common_templates -> kubevirt_ssp_common_templates_restored_total (also move the action of "restored" after the entity the metric is about)
kubevirt_vmi_filesystem_total_bytes -> kubevirt_vmi_filesystem_capacity_bytes_total (also added capacity)
