Docker need to be installed

1. Deploy service to host (or run it locally)
2. Implement custom JSON schema, put it to /schemas directory (or use "example.json" for test)
3. Execute GET {host:port}/example/users/666
4. Obtain response: ""id": 666, "name": "John Wick", "email": "johnwick@gmail.com""

It's possible to share data between Flask request contexts via Redis cache if request have same key

1. Execute POST {host:port}/cache/users with some json body: f.e., {"email": "rickastley@gmail.com"}
2. Obtain response ""id": 123, "status": "ok""
3. Execute GET {host:port}/cache/users/123
4. Obtain response ""id": 123, "email": "rickastley@gmail.com""

So emailparameter value was shared between two unrelated Flask contexts
