docker_container: fix various idempotency problems and non-working options (#45905)

* Sorting args.

* Doing comparisons of options with container parameters in a more context-sensitive way.

This prevents unnecessary restarts, or missing restarts (f.ex. if parameters are removed from ``cmd``).

* Make blkio_weight work.

* Fix cap_drop idempotency problem.

* Making groups idempotent if it contains integers.

* Make cpuset_mems work.

* Make dns_opts work.

* Fixing log_opts: docker expects string values, returns error for integer.

* Adding tests from felixfontein/ansible-docker_container-test#2.

* Make uts work.

* Adding changelog entry.

* Forgot option security_opts.

* Fixing typo.

* Explain strict set(dict) comparison a bit more.

* Improving idempotency tests.

* Making dns_servers a list, since the ordering is relevant.

* Making dns_search_domains a list, since the ordering is relevant.

* Improving dns_search_domains/dns_servers.

* Fixing entrypoint test.

* Making sure options are only supported for correct docker-py versions.
