Add Istio JWT Authorization

[jurabek]

Problem

Currently, JWT token authorization implemented on each service separately, which is very hard to maintain or change

Solution

Instead, we can use a JWT Auth feature from Istio with Envoy Auth proxy

Requirements

• Istio must setup in prod
• Locally not possible to test Roles and Rights

Since I finished bootstrapping backend and frontend, I will prioritize infra topics
