Script wasn't able to handle path that Packer used to create VM in the first place:
"==> hyperv-iso: Copying to output dir...

Used path was: C:\Users\HANNU~1.PIK\AppData\Local\Temp\packerhv616791918\export253729206\2016min

When using the raw image format and attempting to resize it we get the following error message:
```
WARNING: Image format was not specified for 'test.raw' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
```
Specifying the format will remove this warning.
Documentation for ebssurrogate states that all of the devices in
`launch_block_device_mappings` are snapshotted and included in the
image. In fact, only the device that was designated as the root
device was snapshotted. This patch modifies the builder to create
snapshots of all the devices and include them in the image. This
allows creating images with separate filesystems preconfigured,
rather than having to add volumes to `ami_block_device_mappings`
and configure them after boot.
RFC952 restricts hostname not to use underline(_) and period(.), so
private cloud with legacy DNS system does not allow just to use
image_name for name of server.
Add instance_name config option for servers which packer creates to
make instance_name configurable. If instance_name is not specified,
by default it works like the past using image_name for instance_name.
