Optimize and refactor project

[kgromov]

• Changes for dependencies and parent pom:
  • set java version as 17 and move maven compiler version to parent
  • remove redundant jackson-core depenency - since it's transitive to jackson-databind
  • remove src from parent - parent is declaration not implementation
• Take advantage of lombok (yes it was in dependencies but not used :smile: ):
  • log
  • dependency injection with @RequiredArgsConstructor (btw some dependent components were even not final but injected with constructor)
• Other refactoring and fixes:
  • Move event source to try with resources to close it after defined timeout
  • Replace topic configuration with default topic
  • Move source stream uri to configuration
  • fix properties file - wrong separator of key/value was used - it's not a .yml :smile:
