Commit 3fc2defb6 altered the directory structure associated with an
exported VM. The changes mean that the export process now stores the
exported machine files and folders under a folder with name 'vm_name' in
the output directory.
This commit restores the previous behaviour whereby the exported machine
files and folders were stored directly in the output directory. This
allows us to keep the efficiency improvements introduced with 3fc2defb6
while maintaining backward compatibility.
By default the Export-VM command creates three folders in the specified
export directory - 'Virtual Hard Disks', 'Virtual Machines' and
'Snapshots'. When a machine with no associated snapshots is exported the
'Snapshots' directory is empty.
Prior to 3fc2defb6 the Snapshots folder was not copied/incorporated into
the output directory at all. This was a bug.
This commit preserves the legacy behaviour by not including an empty
Snapshots directory in the export. However, if there *are* Snapshots
associated with the VM, they are now moved into the output directory
along with the usual directories containing disks and VM metadata. This
prevents warnings/errors on import due to missing snapshots.
