Change license to GPL version 3 or later

[janvhs]

The Trento team decided to change the license of the checks to GPL or later. This change is done to keep the checks copyleft during future changes

I have do double check, that only SUSE employees committed to the checks in the Wanda repo, then this should be it. Otherwise AFAIK we would need to get their OK or leave files they worked on as Apache2 licensed.

I tagged you all to ensure there is no other obligations :D "Speak now or remain silent forever" or something like that

The content of the LICENSE file is supposed to contain the copyright notice stating under which license the software is distributed, not the license itself.

Look at how it was done for the Apache license, and follow the instructions at the bottom of the license text, in the "How to Apply These Terms to Your New Programs" section.

You can omit including the license itself in our source tree, and just put a link to it in the notice.

@stefanotorresi Maybe it is different with Apache, but with GPL you put the whole license text into the LICENSE or COPYING file. See https://gitlab.gnome.org/GNOME/gnome-terminal, https://github.com/openSUSE/snapper/blob/master/COPYING or a GNU program https://git.savannah.gnu.org/cgit/tar.git/tree/COPYING for reference.

There is zypper, which does it in a similar way to what you proposed, https://github.com/openSUSE/zypper/blob/master/COPYING . Please have a look and pick one of those options

This has nothing to do with the license: the copyright information notice and the license itself are two different pieces of documentation, and they can live in different places. In our case, we want to only put a link to the actual license, and shorten the notice to something that basically states "This project is licensed this way. If you want to read the license, here is a link".

Exactly, this is very similar to what I am requesting, and it's consistent with how we do it in the other repos.
I don't think we need to rename the LICENSE document to COPYING, but if you feel strongly about it (I can agree that technically the document is not the license itself, but copying instructions), then do it, but you'd need to do it for all the repos to keep consistency.

Almost there, a few tweaks before we're done.

@stefanotorresi It's directly copied from the GPL license, but I can do that
