[Feature Request] Disk sizes

Could the report also contain the disk sizes?

I understand that the relationship between VM and disks is 1to N and that it could be an issue.
I guess the disk sizes could be concatenated into one single string to fit into a single column, something like:
```
...,nics,disks,disk sizes,...
...,2,2,disk0 20GB | disk1 10GB,...
```

Thanks
