Update labels.json v2

[zdeveloper]

labels.json has been a great start with key/value structure, however, as we look into expanding, we want it to accommodate for more dynamic structure, please update the code base to follow the following format

[
  {
    "label": "nbs_patient_id",
    "type": "text",
    "color": "0,0,255"
  }
]

Acceptance Criteria

Update all existing labels.json to this format Update all pipeline classes to access this format Update api to use this format
