Send JWT token expiration date along with APIs response

[isabelcosta]

Description

As a developer/consumer,
I need send the JWT token expiry date,
so that I can, be aware of the expiry date when I receive the access_token.

Send the expiry date of the token along with POST /login response.

Current login response structure:

{
      "access_token": "YOUR_TOKEN",
}

New login response structure:

{
      "access_token": "YOUR_TOKEN",
      "expiry": "EXPIRY_DATE_UNIX_TIMESTAMP"
}

Acceptance Criteria

Update

• Update current to new response returned by the Login API
• Decide on JSON response structure (discuss on slack's #mentorship-system channel)
• Update Swagger Documentation file

Definition of Done

• All of the required items are completed.
• Approval by 1 mentor.

Estimation

4 hours

@m-murad @Dilu9218 I created this issue referring to @m-murad 's comment.
To do this I'll study the JWT flask extension to see how to do this and discuss on slack the appropriate response structure.

This blog post's section "Authentication Response Handler" helped me do this.
