Schema for the VM payload config
Since we don't have a standard for JSON schema yet, protobuf is used
here to describe the schema for the VM payload config.
For now, it conveys
- version (1 for the current schema)
- os.name (microdroid is the only valid value )
- task.{command, args}
- apexes[].name (e.g. com.android.compos)
