Previously, cdist would silently swallow the error (no invalid config file was
generated).
Reason: `set -e` does not exit if a command in a sub-command group fails,
it merely returns with a non-zero exit status.
e.g. the following snippet does not abort the script if sshd -t returns with a
non-zero exit status:
set -e
cmp -s old new || {
# check config file and update it
sshd -t -f new \
&& cat new >old
}
or compressed:
set -e
false || { false && true; }
echo $?
# prints 1
As discussed in the chat, this type now supports a broader list of OSes
which it supports backports for. Because of this, it was renamed to
something more generic. "apt" should fit in.
Because the sourced explorer can't be detected by shellcheck, it will be
completely disabled. Changing the path to /etc/os-release isn't
deterministic either.
The shellcheck wiki page suggests to use `source=/dev/null` instead of
`disable=SC1090`, but it was choosen to completely avoid that check ..
Because the function already exists, it will be used for the file to be
changed, too. Therefor, no quotes are required for that value.
The prefix and suffix match was also improved: There is no regex check
any more (the regex did checked the whole line); instead it will do it
simple.
importlib has been a thing since Python 3.1, and imp has been deprecated since
3.4.
Insert random complaint here about not being able to use f-strings because they
were introduced in Python 3.6 and apparently we support Python 3.5 >,<.

This changes the here-document to do not interpret any shell-things. It
also single-quotes some more strings that are printed to code-remote.
Fixes#838
Because it currently only support IPv4. To implement this, it falls back
to IPv4 for backward compatibilty, but now supports rules for IPv6 and
both protocols at the same time.
