Lists in JSON responses do not have root level keys

For Example:
GET /assemblies
[
    {
        "status": "READY",
        "plan_uri": "http://localhost:9003/v1/plans/a5e679bb-0f53-4245-ab71-db095664a22a",

        "name": "test",
        "application_uri": null,
        "tags": null,

]

However, the list should have a key associated with it as show below. This will be necessary when pagination is implemented and other attributes such as "next" and "previous" are added.

{
   "assemblies": [
       {
           "status": "READY",
           "plan_uri": "http://localhost:9003/v1/plans/a5e679bb-0f53-4245-ab71-db095664a22a",
