Breaking change: CustomerSsoService 

## Changes
Call the customer-sso trough ApiGateway instead of a direct call.

Old endpoint was going straight to FT Core and key were issued by FT Core teams.  
The new endpoint goes through the apiGateway and therefore a new key is required, in the TYK format.

Adaptation: The two endpoints we call in the customer-sso service are returning responses without body.
For this reason, the code in make-request.ts had to be changed to expect responses with empty body.
