Add sort_results.py, linking to custom dsl in sort component config

[CWDamm-Kint]

This is the local implementation for custom sort orders (see archesproject/arches#11780.

If the config of the Sort search component contains custom dsl, then this is used to determine how Arches sorts the data in the main search page.

The DSL for Jersey's custom sort order (exact graph order tbc) is:

{
  "dsl": {
    "type": "number",
    "script": {
      "lang": "painless",
      "params": {
        "order": [
          "243f8689-b8f6-11e6-84a5-026d961c88e6",
          "99417385-b8fa-11e6-84a5-026d961c88e6",
          "3af584c3-fd4d-11e6-9e3e-026d961c88e6",
          "24d7b54f-5464-11e9-a86b-000d3ab1e588"
        ]
      },
      "source": "List order = params.order; int index = order.indexOf(doc['graph_id'].value); return index != -1 ? index : order.size();"
    }
  },
  "field": "_script"
}
