Support for Docker rootless

[GHDEV00]

Would adding support for Docker rootless mode be possible?

There was an old issue that got closed because CIS didn't include it in its release but CIS Docker v1.7.0 includes it in the check "2.1 Run the Docker daemon as a non-root user, if possible".

Old issue: #505
CIS reference: https://workbench.cisecurity.org/sections/2370444/recommendations/3808700

Hi @GHDEV00, checking if the docker daemon runs rootless isn't a big issue but the follow-up is to support rootless checks, or a combination of both, which is harder.

Hi @konstruktoid, I see that support for rootless checks need work. Would it be possible to at least add this as a feature request? I think many users would benefit an implementation of such checks, as docker rootless mode is one of the key aspects when securing a docker installation.

Of course!
We'll keep this issue open, and if you want to send a PR, that would be great as well.
