This might be slightly controversial, in that you must specify the state
if a file would need to be created to perform the action. We no longer
implicitly assume that just specifying content is enough. As it turns
out, I believe this is safer and more correct. The code to implement
this turns out to be much more logical and simplified, and does this
removes an ambiguous corner case from the reversed resource code.
Some discussion in: https://github.com/purpleidea/mgmt/issues/540
This patch also does a bit of related cleanup.
While writing docs, I couldn't remember what the correct style was
supposed to be, and I remember someone complaining about this
previously, so I decided to add a linter! I excluded a bunch of annoying
style rules, but if we find more we can add those to the list too.
Hopefully this gives us a more consistent feel throughout.
This does some cleanups and moves some things around for a better
experience. If you're an expert in this area, or are a new user who has
some feedback about their first impressions and experiences, please let
