This commit implements the `manifest` command for `image-builder`.
It will generate an osbuild manifest based on the given inputs,
e.g.:
```
$ ./image-builder manifest centos-9 qcow2
{"version":"2","pipelines":[{"name":"build","runner":",...
```
Note that there is an integration test but because of the depsolve
it will be slow. It will be skipped when doing `go test -short`.
