[INS-131] Add response id and response name to Postman metadata

[mustansir14]

Description:

The PR adds response_id and response_name to the Postman source's metadata protos and captures these fields from the response item.

Checklist:

• Tests passing (make test-community)?
• Lint passing (make lint this requires golangci-lint)?

response.Uid is already being stored in m.FullID field. Could you help me understand the reason behind storing the same value in another field, i.e., m.ResponseID?

[mustansir14]

This is the pattern that has been used all over this source. For example, see for request ID.

FulID is supposed to contain the ID for the item (whatever it may be, request, response, folder etc) while the specific fields like RequestID and ResponseID are supposed to contain IDs of these specific items.

To add to @mustansir14's comment, FullID isn't present in the proto definition of Postman either, and is being used internally to form the full Link to the postman item so the response ID and name doesn't actually make its way outside of the code.
