Certain installations may not have this. Without this, the step
where `/etc/apt/sources.list.d/docker.list` will fail and write
garbled data to the file, potentially breaking apt.

This started as a "fix some links", but reading the section, I found various
issues that could use some improvement. After that, I noticed that both the
Windows and Mac pages had the same content, so I moved this to a common page
instead.
Note that there's still additional information that should likely be included
(and perhaps a rewrite into "per topic" headings (containers, images, ...).
Things that are missing;
- backup/restore swarmkit configs
- backup/restore swarmkit secrets
- backup/restore CLI configuration, trust data etc.
What I did in this pull request:
- recommend pushing images to Docker Hub as the default approach to back up
images (but kept `docker image save` as an alternative)
- recommend `docker container commit` to save containers to an image, as doing
so preserves both the container's configuration _and_ filesystem changes.
`docker container export` only preserves the filesystem, but all other
configuration is lost, which makes it hard to restore a container from it.
Using `docker container commit` (committing the container to an image) also
allows to follow the same procedure to backup containers as for images
(both allowing them to be pushed to a registry, or to a file).
- added some information about "wether or not" containers should be backed
up, as it may not be needed to back up containers if all data is stored
in volumes (best practice).
- added some warnings regarding "sensitive data" (environment variables),
and links to making repositories private before pushing.
