- generally people refer to a plain disk image as `raw`
- `gcp` is shorter and it is the only image type supported
- remove `img-gz` as it is not needed. It does not really save space
as you have to build the full image and compress it anyway. On
many platforms the `raw` image will be a sparse file anyway,
even on the Mac soon.

This is a little ugly in terms of the validation now, but it is a move towards
splitting "build" and "package".
The "tar" output (and soon others) can output direct to a file or to stdout.
Obviously you can only build a single output format like this.
The LinuxKit output formats that build disk images cannot stream as they
have to build whole images. These allow multiple outputs.
In future we will probably change to
```
moby build | moby package
```
or similar, but that is a bit ugly, so currently have a compromise where
there are essentially two output types.

GCP does not recognise the images, even though they appear identical to those made
by libguestfs and work on qemu fine. Their validation code does not like them for some
reason.

- does not require docker if user has qemu natively, will still fall back to docker
- allow specifying size for fixed size disk images
- add a raw disk output format
- more dogfooding
- marginally slower, but can be improved later
The images used to do the build are cached to make the process quicker.

This removes outputs from yaml, instead you can do
```
moby build -output tar -output qcow2 file.yaml
```
or alternative syntax
```
moby build -output tar,qcow2 file.yaml
```
In future we may change this to be available in a `moby package`
step, but lets try this for now.

Using the label `org.mobyproject.config` will use that JSON
(or yaml, but it is very hard to get yaml into a label as newlines are
not respected) for parameters that are not explicitly set in the yaml file.
Had to change parameter definitions so override behaves as expected.

This is a fairly generic bootable disk with syslinux. Should
work if you dd it onto a USB stick, and should also work for AWS.
You need to uncompress it of course! Default size is 1G.
Will add cli option to set the size once I split out `moby build`
and `moby package` shortly.

Add a canonical single tarball output format. This
adds kernel and cmdline to `/boot` where LinuxKit output
formats will find them.
Make the other output formats use that as a base.
