In JSON API, representation of multiple similar objects are in arrays form,
is problematic.

For example,in entrypoint /api/hosts:
The XML for options under power_management is:
<options>
    <option name="port" value=""/>
    <option name="secure" value="false"/>
</options>

but the JSON representation is:
"options" : {
        "options" : [ {
          "name" : "port",
          "value" : ""
        }, {
          "name" : "secure",
          "value" : "false"
        } ]
      }

so options inside powerManagement is an object containing an "options" field which is an array of objects.

I think it should be that options field of powerManagement is an array of objects directly.

This is happening in other locations too, I think the code groups similar xml objects in a single json field with plural form name. in cases where it's the only type of elements, it should be grouped directly.
