deps: Refactor dependencies (#3224)

* remove spring dep
move junit, logging, mockito under dep mgmt

* upgrade anti-corruption-layer deps

* async method invocation

* balking, bloc

* bridge to bytecode

* caching

* callback - cqrs

* component - health check

* hexagonal - metadata mapping

* rest of the patterns

* remove checkstyle, take spotless into use
