Research monitorings on core functionality

[Deimoz]

Think about monitorings of the project

Possibilities:

1. Load monitorings with Prometheus + Grafana https://habr.com/ru/articles/709204/
2. Monitoring on logs with Sentry https://habr.com/ru/articles/507644/

Second option has higher priority right now because of easy use Sentry can be implementet in project with log4j https://github.com/getsentry/examples/tree/master/java/log4j-2.x

So after https://github.com/Clu0D/NewsSummarizerBot/issues/8 the task is:

• Update log4j configuration with the Sentry appender. example
• Add script for Sentry startup. Can be found here (maybe it is possible to start it with our docker)

If possible add docker-compose Sentry file and intagrate it with our app

Booted up sentry localy

We can define our alert rules and set different filters such as filename or message
