You should only use the "shell" module when you need shell functions
like flow control and redirects. Also, the "command" module is safer
because it is not affected by the user's environment.
Something seems to have happened as of Ansible 2.4.0.0 where this no
longer works. I suspect it is related to the major changes to static
and dynamic imports that landed around this same time.
In practice this achieves the same function, but without the "magic"
ability to use one task for different operating systems.

We make sure that this tasks always runs by using the special tag of
the same name.
[ANSIBLE0006] systemctl used in place of systemd module
Also, move the functionality of the changed check to the systemd task,
because it has the ability to simply daemon-reload itself now.
I can't remember right now why I needed to use Debian's MariaDB build
but now I just want to use upstream's latest stable. Debian's version
is 10.1 and upstream has moved on to 10.2.
Ansible 2.4 changes the way includes work. Now you have to use "import"
for playbooks and tasks that are static, and "include" for those that
are dynamic (ie, those that use variables, loops, etc).

Using www-data was a temporary measure while I was waiting for the
official nginx.org packages to be released for Debian 9 and we had
to use Debian's own nginx package.
Sync with latest packaged version from Debian 9. Effectively this
only updates comments and disabled options, but having less changes
to look at during an apt upgrade is nice and reduces the chance of
adding errors.
There are currently no nginx.org builds for Debian 9, so we need to
use the package from Debian's repository. This package provides a
www-data user and group instead of an nginx one.
We can revert some of this after Debian 9 is released and official
builds come from nginx.org (though it might be useful to keep the
main nginx.conf as a template).
Debian 9 is still in beta and doesn't have nginx.org builds yet, so
we need to use the nginx package in Debian's repositories, and that
required a bit of a different configuration.
After official nginx.org builds are released we can revert this.
I'm surprised this worked all these years actually. Since Ansible
version 1.6 it has been possible to use the version_compare filter
instead of doing math logic on strings.
