Support for exporting/saving current request to disk

[dropdevrahul]

• Should allow saving current request along with the response and body to disk.
• Format options:
  • Custom Json: not very useful
  • Postman json: have to check postman license to see if it's allowed
  • Openapi Spec: will take a lot of time and effort

So for now we can use a custom JSON and add more options with more contibuters.

There is something wrong with the export and it's writing as escalated permission
