[Improvement] Add equals method to GravitinoVersion.java

[justinmclean]

What would you like to be improved?

GravitinoVersion.java implements and overrides compareTo but not equals and this may lead to different results in different versions of Java depending if the underlying code uses compareTo or equals.

How should we improve?

Add equals method.
