Optimize Patient Info Form

[meghanmc]

In order to make the code for PatientInfoForm more compact and easily extendable, we should use a format similar to that used in DiagnosisForm.

• create a JSON to store the form fields as

  {"PatientInfoFields": [
  "fieldType" : "fieldName",
   ...
  ]
  }

• Render the PatientInfoForm components based on the content of the JSON file
