Tomasz Posluszny 6528ecc800 Add event listeners to RocksJava (#7425) 
Summary:
Allows adding event listeners in RocksJava.

* Adds listeners getter and setter in `Options` and `DBOptions` classes.
* Adds `EventListener` Java interface and base class for implementing custom event listener callbacks - `AbstractEventListener`, which has an underlying native callback class implementing C++ `EventListener` class.
* `AbstractEventListener` class has mechanism for selectively enabling its callback methods in order to prevent invoking Java method if it is not implemented. This decreases performance cost in case only subset of event listener callback methods is needed - the JNI code for remaining "no-op" callbacks is not executed.
* The code is covered by unit tests in `EventListenerTest.java`, there are also tests added for setting/getting listeners field in `OptionsTest.java` and `DBOptionsTest.java`.
