Add exceptions for USE_DATA_CLASS: hibernate Entity and probably others

[petertrr]

There are cases when using data class is not recommended by a particular library. We should either add them into the code or add a way to specify a set of annotations, that effectively suppress this rule.

Also we got a similar report here: #1316

Simple Suppress does not help?

[petertrr]

It sure does, but this way every new developer should know that they need to place that Suppress annotation and that they don't need a data class, even though diktat suggests it. There is no obvious way for repository maintainer to enforce such a rule.

Should be fixed by #1328 (can now be configured)
