Remove copyright and author in java files?

[renedupont]

Is your feature request related to a problem? Please describe.
I noticed that many java files have a huge text at the beginning regarding Copyright and also an author annotation above the class name.
I want to raise and discuss the question if these copyright mantras are really necessary there, because if not I'd see them as a huge chunk of code noise.
Regarding the author annotation I share the opinion of https://www.vojtechruzicka.com/stop-using-javadoc-author-tag/#what-is-wrong-with-author and would remove them altogether. Any objections to this?

Describe the solution you'd like
Remove author annotations. Clearify if copyright text can also go away.

Describe alternatives you've considered
Leave it like it is.

@michaelsauter @clemensutschig do you know why the copyright header was added to the prov app classes? Can we remove the copyright header? How do we handle copyright in ods?

Sorry I don't know - would need to look into what is required or not.

The author annotations were removed by PR #639.
I read a bit about the copyright notice and I am still not 100% sure about this, but for a project there is the LICENCE.md file which we also have, but that it could also make sense to put a notice in each file for cases where people take only parts (or files) of the project. I looked at the google guava lib on github as an example and they have both, a LICENCE.md file and a notice in every source code file.
