BUGFIX: Sort numeric rack and rank numerically

This will sort multi-digit rack and rack so that this:
```
HOST           RACK RANK APPLIANCE OS   BOX      ENVIRONMENT OSACTION INSTALLACTION COMMENT
stacki-667-123 0    0    frontend  sles frontend ----------- default  default       -------
stacki-667-14  667  14   backend   sles default  ----------- default  console       -------
stacki-667-15  667  15   backend   sles default  ----------- default  console       -------
stacki-667-5   667  5    backend   sles default  ----------- default  console       -------
stacki-667-6   667  6    backend   sles default  ----------- default  console       -------
stacki-667-7   667  7    backend   sles default  ----------- default  console       -------
```

Will now be sorted in rack order, like this:
```
HOST           RACK RANK APPLIANCE OS   BOX      ENVIRONMENT OSACTION INSTALLACTION COMMENT
stacki-667-123 0    0    frontend  sles frontend ----------- default  default       -------
stacki-667-5   667  5    backend   sles default  ----------- default  console       -------
stacki-667-6   667  6    backend   sles default  ----------- default  console       -------
stacki-667-7   667  7    backend   sles default  ----------- default  console       -------
stacki-667-14  667  14   backend   sles default  ----------- default  console       -------
stacki-667-15  667  15   backend   sles default  ----------- default  console       -------
```
