Custom filters available for the “ResourceBase” opaque filters

[afabiani]

• Depends on: Extend the ResourceBase metadata model with an opaque JSONField #8689
• Targets: 3.3.x

Extend the angular based filter types and the CommonModelAPI tastypie resource based filters in order to be able to dynamically create filters shortcuts associated to the obfuscated JSONField, e.g.:

Ideally the JSON structure returned by the view in order to build the filter should be something like:

{
  "custom_filters_label": [
    {
      "filter_one": {
        "param_label": {
          "en": "a"
        },
        "param_key": "b",
        "param_value": "c"
      }
    }
  ]
}

For the example above the final JSON would be something like:

{
  "Sensor Parameters": [
    {
      "uom_filter": {
        "param_label": {
          "en": "Unit of Measure"
        },
        "param_key": "uom"
      }
    }
  ]
}
