A reverse proxy (REST -> gRPC) Golang microservice.
This service's sole purpose is to act as a gateway with a reverse proxy mapping a REST API to gRPC functions.
[] Read a session cookie from the incoming request
[] Read session from the users-service via a sessionID (from cookie)
[] Build a JWT with the userID + authorisation data
This JWT will be encoded per request, and will be shortlived (only alive for the request). The tokens claims should be serialised with user data + the sub should contain the UserID.
[] Pass JWT via a ctx through to gRPC calls in services down the line (eg task-service).
