Adds more labels to the Dockerfile

It also updates the README and the bug_report template to reflect
the changes. Additionally, in the README some relevant shields from
shields.io are added.

The labels follow [label-schema.org][lsorg] and the [OpenContainer
image spec, section annotations][ocis], specifications.

[ocis]: https://github.com/opencontainers/image-spec/blob/master/annotations.md
