Write aRMT protocols in app config service

[blootsvoets]

This could be a JSON editor at first, and possibly a fully-fledged form at a later stage. Protocols should be available at least on a project-level, but perhaps it could even be supported on every level (global, project, user).

Possible API:

Get/set the protocol for a given user:

/projects/{projectId}/users/{userId}/protocol/{clientId}
---
{
  "version": "0.1.1",
  "schemaVersion": "0.1.0",
  "name": "test",
  "healthIssues": [
    "general"
  ],
  "protocols": [
    {
      "name": "test",
      "showIntroduction": false,
      "questionnaire": {
        "repository": "https://my-url",
        "name": "test",
        "avsc": "questionnaire"
      },
      "startText": {
        "en": "Time for a new questionnaire!",
        "nl": "Tijd voor een nieuwe vragenlijst!",
      },
      "endText": {
        "en": "Thanks for filling this out!",
        "nl": "Bedankt voor het invullen!",
      },
      "estimatedCompletionTime": 10,
      "protocol": {
        "repeatProtocol": {
          "unit": "year",
          "amount": 9999
        },
        "repeatQuestionnaire": {
          "unit": "min",
          "unitsFromZero": [
            482	
          ]
        },
        "completionWindow": {
          "unit": "min",
          "amount": 10
        }
      }
    }
  ]
}

And likewise, on the project level /projects/{projectId}/protocol/{clientId} and on the global level /global/protocol/{clientId}.

Get/set the JSON schema for a given client

GET /global/protocol/{clientId}/schema

HTTP 200 OK
{
    ... json schema ...
}
