* refactor(data_classes): remove duplicated code

Remove overriding methods that have the same code as the overriden ones.

* refactor(data_classes): further remove duplicated code

Manually checked with:

    $ pip install pylint
    $ pylint --disable=all --enable=R0801 --min-similarity-lines=1 aws_lambda_powertools/utilities/data_classes

* refactor(data_classes): Add comments
