[ALS-7751] Java Opts can now be passed to docker container (#52)

* Add MemoryCheck service for monitoring max heap memory
* Replace System.out with SLF4J logger in MemoryCheck

Updated the MemoryCheck class to use SLF4J logger instead of System.out for logging max heap memory. This enhances logging consistency and allows better integration with logging frameworks.
