Updated kubevirt metrics names

Updated kubevirt metrics names:

kubevirt_vmi_vcpu_wait_seconds to
kubevirt_vmi_vcpu_wait_seconds_total

kubevirt_vmsnapshot_disks_restored_from_source_total to
kubevirt_vmsnapshot_disks_restored_from_source

kubevirt_vmi_memory_swap_in_traffic_bytes_total to
kubevirt_vmi_memory_swap_in_traffic_bytes

kubevirt_vmi_memory_swap_out_traffic_bytes_total to
kubevirt_vmi_memory_swap_out_traffic_bytes

 The following query can identify virtual machines that are waiting for Input/Output (I/O):

 Returns the wait time (in seconds) for a virtual machine's vCPU. Type: Counter.
 
 A value above '0' means that the vCPU wants to run, but the host scheduler cannot run it yet. This inability to run indicates that there is an issue with I/O.
