Onboarding: Setup a micro service which handles confidential stuff

At this moment, we are running Qt ci plugin from user's computer and it's not safe to store secrets there. So, we should create a micro service and use this to retrieve credentials from the secret service.

We have to deliver: 

• Python FastAPI implementation of following endpoints:
  • <server>/api/has-qtcloud-licence
    • params: Qt account email, Qt account password, plus some sha1 or hash for authentication to microservice?
    • internally:
      • Use discovery api
      • Login and get JWT token
      • Check if user has licence for Qt cloud
      • Return TRUE or FALSE
      • If TRUE, also return conan credentials
  • <server>/api/get-git-admin-token
    • params: some sha1 for authentication
    • internally:
      • return the git.qt.io's admin token
  • (more end points to be checked)
• Use a python3 alpine image in a dockerfile, copy this server there
• Execute the server using Python FastAPI

IMportant: This MicroService should already contain the Login CODE for Qt account. So, we are going to send the Qt account + Password to this microservice and this uses the Qt account apis (discovery + login) etc to return relevant information for us to use in the Qt ci plugin code. 

A docker file implementation is required so that the microservice can be executed locally or in production.
