1. This needs a changelog fragment.
2. The remaining sanity error (no-log-required) will be fixed by docker_swarm_service: flag secrets option as not secret #102, just ignore it.

Happy to merge it when the changelog is updated.

Added, and squashed into one commit. Thanks!

@felixfontein can you take a look at why tests are still failing? #102 has been merged.

[felixfontein]

@WojciechowskiPiotr they failed because collection installation from galaxy failed (after three trials). That seems to happen a lot more since yesterday or so (ansible/galaxy#2429). Once the suggestion is merged tests will run another time anyway, and if some fail again I'll kick them until they pass :)

Happy to merge it when the changelog is updated.

Everything looks good to me (but then I'm not that familiar with Docker swarm), so feel free to merge.

I'll create a new release once this is merged to get the security fix out.

@sgpinkus thanks for fixing this!
@WojciechowskiPiotr thanks for reviewing and merging!
