Skip testing setters for Enums

[niravmsh]

Having setters in Enums is considered a bad practice and flagged by systems like PMD
There is no way to skip Setter checks on Enum at the moment
Specially when Enums are nested inside other pojos which are been tested for Setters

I agree, in the future we can skip testing setter for enums by default. For now you can workaround this in simple way method(EQUALS, HASH_CODE, GETTER, TO_STRING, CONSTRUCTOR) so I wont prioritize this issue.

But @niravmsh you are welcome to implement this now.

You can even think about including / excluding tests for methods e.g.:

testMethods(EQUALS) / includeTestsFor(EQUALS) / include(EQUALS)
doNotTestMethods(EQUALS) / excludeTestsFor(EQUALS) / exclude(EQUALS)

It will be nice improvement to pojo-tester

Thanks!
