The value 4 should not be allowed in as a value in security_objectives

[gbyx3]

When creating assets via the api (POST /api/assets/) the security_objectives values is not properly validated.
It checks for an integer but not for a max value of >=3.
This causes an internal server error and the asset page fails to load.
This issue is similar to #1329, the fix for this issue does not solve this.

To Reproduce
Steps to reproduce the behavior:

1. Make a POST request to /api/assets/
2. Payload:

{
  "is_published": true,
  "name": "Some name",
  "type": "PR",
  "folder": "<CHANGE ME>",
  "security_objectives": {
    "objectives": {
      "confidentiality": {
        "value": 4,
        "is_enabled": true
      }
    }
  }
}

3. Refresh the Assets page under Organization
4. See error

Expected behavior
Block the request with "4 is not a valid integer for value"...
