roles/nginx: Force amd64 builds on apt sources
Avoids the following error in apt:

Skipping acquire of configured file 'nginx/binary-i386/Packages' as repository 'https://nginx.org/packages/ubuntu bionic InRelease' doesn't support architecture 'i386'

roles/nginx: Use bionic builds on Ubuntu 18.04
NGINX finally published builds for Ubuntu 18.04 "bionic" so we don't
need to use the 17.10 "artful" ones anymore.

roles/nginx: Allow custom resolvers for TLS stapling
Allows to specify custom DNS resolvers for TLS stapling, with a default
of Cloudflare's public DNS servers.

roles/nginx: Default to Cloudflare public DNS for TLS stapling
No need to give Google even more data or free advertising by using
this as the default! In practice I always use the DNS servers from
the VPS provider anyways.

roles/nginx: Use set_fact to set certbot dependencies
Instead of looping over a list of items to install, we can actually
just give a list directly to the apt module. This allows the module
to install all packages in one transaction, which is faster as well
as slightly safer for some dependency resolution scenarios.

roles/nginx: Add name to Let's Encrypt task

tasks.

roles/nginx: Move WordPress tasks to separate file
Because of the shift from static imports to dynamic includes these
tags will never be reached unless they have their own task that is
tagged at the top-level (dynamic includes don't pass their tags to
their children).

roles: Remove unreachable "packages" tags
After reörganizing for dynamic includes these tags will never be reached
because the children of dynamic includes do not inherit tags from their
parents as they did with static imports.

roles/nginx: Use dynamic includes for Let's Encrypt
As of Ansible 2.4 and 2.5 the behavior for importing tasks has changed
to introduce the notion of static imports and dynamic includes. If the
tasks doing the import is using variable interpolation or conditionals
then the task should be dynamic. This results in quicker playbook runs
due to less importing of unneccessary tasks.

One side effect of this is that child tasks of dynamic includes do not
inherit their parents' tags so you must tag them explicitly or a block.

Also, I had to move the letsencrypt tasks to the main task file so the
tags were available (due to dynamic tasks not inheriting tags).

roles/nginx: Use dynamic include_tasks for Let's Encrypt
Use dynamic includes instead of static imports when you are running
tasks conditionally or using variable interpolation. The down side
is that you need to then tag the parent task as well as all child
tasks, as tags only apply to children of statically imported tasks.

roles/nginx: Separate Debian 9 "stretch" Let's Encrypt deps
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.

Update with_items loops to use new-ish "loop" keyword
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.

Adjust playbooks for Ansible 2.4 import changes
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).

roles/nginx: Updates to accomodate Debian 9 (stretch)
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).

Use Ansible's version_compare instead of doing math on strings
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.

roles/nginx: Make sure to set HSTS headers on WordPress static files
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.

roles/nginx: Decrease gzip_min_length from 860 to 256
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.
