roles/common: Add tasks to install tarsnap
Now that Tarsnap has official packages this is one less thing that
needs to be manually installed from source after bringing a machine
up.

roles/mariadb: Use Debian's MariaDB packages for now
MariaDB actually already has Debian 9 (stretch) packages, but they
seem to cause issues with how I'm deploying. I'll skip them for now
I think.

roles/nginx: Update nginx.conf.j2
This is to accomodate Debian's 9 nginx package, as it provides a
different system user/group than nginx.org's packages.

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).

roles/php-fpm: Updates for Debian 9 (stretch)
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.

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.

roles/nginx: Reduce gzip_comp_level from 6 to 5
After performing some tests[0] again I see that level 5 produces
the most acceptable results for my site currently. Others[1] are
using the same, so I'll gladly accept a little less CPU load for
a tradeoff of a few bits of file size.

Set use_letsencrypt to true for nginx role
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.

roles/php-fpm: Only create pools for vhosts that need PHP
Only vhosts running WordPress, etc need PHP. Make sure to set the
appopriate variables for each vhost in the host's vars, ie:

  nginx_vhosts:
    - domain_name:   example.com
      has_wordpress: True

    - domain_name:   example.net
      needs_php:     True

You can set either of them, but not both—needing WordPress implies
needing PHP.

group_vars/all: Disable TLS cipher suites using Triple DES
An attack on Triple DES was recently published[0]. It's not a very
high severity attack but the fact is that Triple DES is very old
and there are much better ciphers to use, like AES and ChaCha20.

I logged the ciphers that were negotiated on all of my vhosts over
a period of 72 hours and there were zero occurences of Triple DES,
so I am removing it, as suggested by the authors of the attack as
well as OpenSSL[1].

roles/common: Add a dedicated playbook for ntp tasks

8851f8f631 Revert "Only update packages indexes if the cache is 1 hour old"
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.
