* Decreasing docker_swarm requirements.
* Fixing docker-py / docker API version requirements, and some comments.
* Add changelog.
* Only send parameters specified by user to docker daemon.
* Extend labels test: not specifying == keep labels.
* Bump minimally required docker-py version for docker_node and docker_node_facts to 2.4.0.
* Prevent crashing when publish or healthcheck is not provided.
* Similarly to docker_swarm tests, only execute docker_node tests on real VMs and restart docker daemon when tests are done.
* Add more tests.
* Added tests for CA options.
* Don't run in docker-in-docker situations where docker daemon becoming instable is really dangerous. Also, restart docker daemon after tests.
* Only run CA tests when openssl_certificate can be run (which is not the case for RHEL7, see #34054).
* Add comment on why docker-based CI runs are skipped.
* Add diff support to docker_swarm.

* Using diff mode for docker_swarm tests. This improves debugging, since the the module now outputs more information on *why* it did certain actions.
Incorporating the abandoned work from PRs #35288 and #45552. Also adding in
the version checking from `docker_container.py`, which should be abstracted
out to `docker_common.py`.

* Improve docker_swarm creation/destruction for tests.
* Fail when conditions aren't met.
* Don't hardcode address for advertise_addr.
