BAEL-1524: Chain of Responsibility Design Pattern in Java (#3780)

* BAEL-1422: measure performance of Random and ThreadLocalRandom using JMH

* BAEL-1422: updated benchmarking examples of Random and ThreadLocalRandom to use newWorkStealingPool that leverages ForkJoinPool

* BAEL-1422: refactored benchmarking examples for comparing performance of ThreadLocalRandom and Random
- initialised the collection of Callable before running benchmarking
- removed for loop for submitting task and instead used executor.invokeAll(collection_of_callable)

* BAEL-1282: added TDD type junit tests for geospatial queries elasticsearch

* BAEL-1524: added example for chain of responsibility design pattern

* BAEL-1524: added BDD style jUnit test to test unknown handler in ChainOfResponsibility design pattern

* BAEL-1524: refactored ChainOfResponsibility design pattern example

* BAEL-1524: refactored ChainOfResponsibility design pattern example

* BAEL-1524: updated ChainOfResponsibility design pattern example

* BAEL-1524: updated ChainOfResponsibility design pattern example

* BAEL-1524: moved chain of responsibility example from core-java module to patterns module
