Configure logging and integrate it with Kibana

[ochaplashkin]

At the moment, we cannot track the behavior of the service, which means that the analysis of problems, correction and testing is delayed and requires huge efforts.

Now we already have an APPserver, but it is not intended for logging.

Checklist:

• add the main logging points at the INFO and DEBUG level;
• debug locally interaction with ELK (or EK, without logstash);
• deploy service;
• update infrastructure/docker/etc;
• setup kibana dashboard;
• update docs.
