Introduce scanning for problematic licenses, patent issues, and similar, in dependencies

[SaschaSchwarze0]

As decided in the community meeting from 2021/11/22, we want to scan for problematic dependencies. Candidate tool is go-licenses. Maybe there is also something in golangci-lint.

We should define the criteria for what is problematic and make sure we get red pull requests if those criteria are violated.
