Debian 9 and Ubuntu 16.04 use the same PHP-FPM configuration so we
can make use of that here.

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: Use explicity booleans for tests instead of "yes" and "no"
Better to be explict with booleans rather than being confused when
you mix up yes and "yes" with Ansible/Python testing of conditionals.

Rename nginx_* variables underneath nginx_vhosts
It's just deduplication, since it's already obvious that the dict
is for nginx-related vars:

    - nginx_domain_name→domain_name
    - nginx_domain_aliases→domain_aliases
    - nginx_enable_https→enable_https
    - nginx_enable_hsts→enable_hsts

roles/nginx: Add HSTS check to vhost template
We need to actually check if HSTS was requested before setting the
header in the block handing PHP requests. We check in the main vhost
block, but nginx headers are only inherited if you don't set ANY
headers in child blocks (ie, headers set in parent blocks are cleared
if you set any new ones in the child).

roles/nginx: Add extra-security headers to PHP block
nginx inherits headers from higher-level blocks UNLESS we also set
headers in the current block. In this case the FastCGI cache header
was being set, so we weren't getting the extra-security ones.

nginx blocks inherit headers set in blocks above them UNLESS the
current level also sets headers[0]. This was causing PHP requests
to not have STS headers because of the FastCGI cache header which
is set in that block.

roles/nginx: Tweaks for vhosts with WordPress
My WordPress blogs have a /wordpress subdirectory in the document
root, but I don't serve from the /wordpress URI.

Technically, all we need is the tweaks to the try_files:
    - `?args` passes query strings to php5-fpm
    - removing 404 from the vhost's try_files so we don't return 404
    when the requested file doesn't exist (obviously not all request
    URI's in WordPress are actual files on the disk)

roles/nginx: Re-work vhost template to support HTTPS
Assumes you have a TLS cert for one domain, but not the others, ie:

    http://blah.com \
    http://blah.net  -> https://blah.io
    http://blah.org /

Otherwise, without https, it creates a vhost with all domain names.
