Add support for maxdistance

[hoffie]

Pull Request (PR) description

This PR adds support for the maxdistance config option which sets the maximum root distance of a source to be acceptable for synchronisation of the clock and may be required in certain setups (some Windows NTP Servers).

This Pull Request (PR) fixes the following issues

I did not find an existing issue for this feature and did not open one as the PR is low-effort and seems straight-forward.

Hum, looks like a lot of variables are duplicated in the module. I'll try to fix this in a PR.

Thanks for the quick review.

I was just following the pattern of all the other config options. Obviously, it's not needed as the tests confirm. I've removed the addition and force-pushed.

Might have been a left-over from the erb -> epp transition in b971db0 where locally-scoped variables might have been needed?

I think you are right.

That looks great to me!
