Instead of iterating over fifteen packages with a loop that does fifteen
separate apt transactions, it is better to give the apt module a list so
it can install them all in one transaction. This is both quicker and te-
chnically more safe for dependency resolution.

Ansible 2.4 and 2.5 are moving away from specialized loop functions
and the old syntax will eventually be deprecated and removed. I did
not change the with_fileglob loops because I'm not sure about their
syntax yet.

I have zero idea if we have IE6 clients any more, but according to the
H5BP community IE6 actually did support gzip and only represents 0.1%
of Internet traffic in 2015 (!) anyways.

[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.
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.
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).
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.

I realized the other day that due to complex logic in the location
blocks, various WordPress static files like images and stylesheets
didn't get the HTTP Strict Transport Security header set. We need
to include it on each level where we are setting headers, because
nginx overwrites headers if you set them again in a child block.
There was some knowledge floating around that 860 bytes was the
optimal size, I think it was from an Akamai engineer or something,
but the HTML 5 Boilerplate server configs use 256 bytes, and I
actually have HTML content that is less than 860 bytes, so I guess
I could benefit from compressing it. gzip compression is costly
for the compression side, but very quick for the client, so this
is a good thing.

The variable name is misleading as this really does is install the
certbot client and its dependencies, and we generally want this to
always happen. If a host doesn't want it, they can override it in
their host vars.
Perhaps I should rename this variable to "bootstrap_letsencrypt" or
something so it is more accurate.
The `ConditionFileIsExecutable` goes in the [Unit] section! This
fixes the error:
systemd[1]: [/etc/systemd/system/renew-letsencrypt.service:6] Unknown lvalue 'ConditionFileIsExecutable' in section 'Service'
Used to indicate if a vhost needs PHP configuration or not, like
for a static site. Set in the hosts's nginx_vhosts block. Defaults
to "False" if unset.
This reverts commit 201165cff6.
Turns out this actually breaks initial deployments, because the
cache gets updated in the first task, then you add sources for
nginx and mariadb, but it doesn't update the indexes because the
cache is < 3600 seconds old, so you end up getting the distro's
versions of nginx and mariadb.
When you give Ansible the key id it will check if the key exists
before trying to download and add it. I got the long fingerprint
from `sudo apt-key finger`.
