   The kvm json schema is wrong, and it was fixed on a certain context, so I'm just dropping the assertion here until the software instance is refactored to use JSON in XML by default.

   This form allows you test any software release on the parameter form.

   This fixes up the support for the json schema definition for {"type": "number",  "enum": [ 1.0,  2.0] }

   It relies on data-format to overcome the limitation of select fields that only output strings on input.value.

   If the field is number the field is handled as float, and not as integer anymore.

   We should use schema_url rather them json_url on validationJSON, since the json_url is the software.cfg.json while schema_url is the actual url for the schema.

  Like in WebSite_login, came_from is an URI Template so we must expand the URI to handle the {&n.me}
  that can be present on the URL.
