[FEDEX] API not returning transit_days or esimated_delivery #739

[danh91]

@vangelow

Describe the bug
Whatever API request I try I never get transit_days and/or estimated_delivery when using Fedex API integration and not Fedex WS (with this one I always get transit days)

To Reproduce
Steps to reproduce the behavior:

1. Make a POST request to /v1/proxy/rates while having a Fedex API (not WS) carrier setup
2. Check for transit_days or estimated_delivery

Expected behavior
Any information about an estimated delivery or transit days is part of the response.

Screenshots
API response example below

Desktop (please complete the following information):

• OS: [e.g. iOS]
• Browser [e.g. chrome, safari]
• Version [e.g. 22]

Additional context
Here you can see that there is not information at all about transit_days - This is one item from the "rates" key of the response

@danh91 Please if there is some idea to trigger the transit days to be returned, because I read something about that being part of the request also give us a sign.
