    VMware: disk_io_limits settings are not reflected when resize
    
    When resize and resize-revirt excute, setting disk_io_limits of
    target flavor. But using VMware driver, disk_io_limits does not
    changed.
    
    On VMware driver, setting disk_io_limits when attach disk.
    But, original is not setting it when resize. So add force
    detach/attach disk when resize. Specifically, the original
    _resize_disk() didn't anything if flavor.root_gb has not
    changed. This is because we need to apply the change of
    disk_io_limits to the virtual machine anytime.
