  1. image-index: remove platform.features field

    While the intended use of the `platform.features` field was to express
    the availability of hardware instructions on CPUs, the practicality of
    expressing and implementing such a standard has been called into
    question. Much of the functionality is usually hidden deep within kernel
    code or is defined by hardware vendors in ways that will make the field
    unusable without future additions. Applications that can make use of such
    field will likely have other requirements on top of this field that are
    specific to a deployment.
    
    In that regard, it is best to remove this field and defer to hardware to
    make the decision about what can be run.
