Implement cd_files option. The Addfile code is modified from the floppy_files

tooling. Tested on OSX, `Windows, and Linux. Documented command line dependencies.
Added acceptance tests (behind testacc flag, since there are dependencies).
This option is only implemented for the vmware and hyperv iso builders. It will be
implemented for others in later PRs in order to make review easier.

// An iso (CD) containing custom files can be made available for your build.
//
// By default, no extra CD will be attached. All files listed in this setting
// get placed into the root directory of the CD and the CD is attached as the
// second CD device.
//
// This config exists to work around modern operating systems that have no
// way to mount floppy disks, which was our previous go-to for adding files at
// boot time.
type CDConfig struct {
// A list of files to place onto a CD that is attached when the VM is
// booted. This can include either files or directories; any directories
// will be copied onto the CD recursively, preserving directory structure
// hierarchy. Symlinks will have the link's target copied into the directory
// tree on the CD where the symlink was. File globbing is allowed.
//
// Usage example (JSON):
//
// ```json
// "cd_files": ["./somedirectory/meta-data", "./somedirectory/user-data"],
// "cd_label": "cidata",
// ```
//
// Usage example (HCL):
//
// ```hcl
// cd_files = ["./somedirectory/meta-data", "./somedirectory/user-data"]
// cd_label = "cidata"
// ```
//
// The above will create a CD with two files, user-data and meta-data in the
// CD root. This specific example is how you would create a CD that can be
// used for an Ubuntu 20.04 autoinstall.
//
// Since globbing is also supported,
//
// ```hcl
// cd_files = ["./somedirectory/*"]
// cd_label = "cidata"
// ```
//
// Would also be an acceptable way to define the above cd. The difference
// between providing the directory with or without the glob is whether the
// directory itself or its contents will be at the CD root.
//
// Use of this option assums that you have a command line tool isntalled
// that can handle the iso creation. If you are running Packer from an OSX host,
// the required tool is is hdiutil which comes preinstalled.
// On linux hosts, you need to have mkisofs.
// On Windows, you must have oscdimg.exe. oscdimg.exe is part of the
// Windows ADK tooks, downloadable from

Floppy drives are no longer supported by generation 2 machines. This requires
you to take another approach when dealing with preseed or answer files. Two
possible options are using virtual DVD drives or using Packers built in web

possible options are using your own virtual DVD drives, or the cd_files option,

When dealing with Windows you need to enable UEFI drives for generation 2

- `cd_files` ([]string) - A list of files to place onto a CD that is attached when the VM is
booted. This can include either files or directories; any directories
will be copied onto the CD recursively, preserving directory structure
hierarchy. Symlinks will have the link's target copied into the directory
tree on the CD where the symlink was. File globbing is allowed.
Usage example (JSON):
```json
"cd_files": ["./somedirectory/meta-data", "./somedirectory/user-data"],
"cd_label": "cidata",
```
Usage example (HCL):
```hcl
cd_files = ["./somedirectory/meta-data", "./somedirectory/user-data"]
cd_label = "cidata"
```
The above will create a CD with two files, user-data and meta-data in the
CD root. This specific example is how you would create a CD that can be
used for an Ubuntu 20.04 autoinstall.
Since globbing is also supported,
```hcl
cd_files = ["./somedirectory/*"]
cd_label = "cidata"
```
Would also be an acceptable way to define the above cd. The difference
between providing the directory with or without the glob is whether the
directory itself or its contents will be at the CD root.
Use of this option assums that you have a command line tool isntalled
that can handle the iso creation. If you are running Packer from an OSX host,
the required tool is is hdiutil which comes preinstalled.
On linux hosts, you need to have mkisofs.
On Windows, you must have oscdimg.exe. oscdimg.exe is part of the
Windows ADK tooks, downloadable from
https://docs.microsoft.com/en-us/windows-hardware/get-started/adk-install#winADK

<!-- Code generated from the comments of the CDConfig struct in common/extra_iso_config.go; DO NOT EDIT MANUALLY -->
An iso (CD) containing custom files can be made available for your build.
By default, no extra CD will be attached. All files listed in this setting
get placed into the root directory of the CD and the CD is attached as the
second CD device.
This config exists to work around modern operating systems that have no
way to mount floppy disks, which was our previous go-to for adding files at
boot time.
