We should have precommit rules to prevent further usage of Guava classes that are available in Java8+

A list replacing Guava APIs with java8 features:

com.google.common.base.Joiner.on()	                        java.lang.String#join() or 
                                                                                         java.util.stream.Collectors#joining()
