The certbot-auto client that I've been using for a long time is now
only supported if you install it using snap. I don't use snap on my
systems so I decided to switch to the acme.sh client, which is imp-
lemented in POSIX shell with no dependencies. One bonus of this is
that I can start using ECC certificates.
This also configures the .well-known directory so we can use webroot
when installing and renewing certificates. I have yet to understand
how the renewal works with regards to webroot, though. I may have to
update the systemd timers to point to /var/lib/letsencrypt/.well-known.
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.

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.
Google's preload check application pointed out that there was an
extra semi colon in the HTTP header:
$ hstspreload checkdomain alaninkenya.org
Warning:
1. Syntax warning: Header includes an empty directive or extra semicolon.

Everything is HTTPS now, whether self-signed or otherwise, so it
doesn't make sense to have a config switch for this.

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

It would be bettwe to set these defaults in the role's defaults, but
we can't because they exist in dicts for each of the host's sites.

The `enable_https` option in host_vars becomes `nginx_enable_https`
to be more consistent with other nginx options used in host_vars.

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).

Include subdomains in the HTTP Strict Transport Security header,
and include the "preload" verb to inform Google we want to be pre-
loaded into the HSTS preload.

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.

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)

Assumes you have a TLS cert for one domain, but not the others, ie:
http://blah.com \
http://blah.net -> https://blah.iohttp://blah.org /
Otherwise, without https, it creates a vhost with all domain names.

Without this, all requests to directory URIs throw 403 errors due
to directory listings not being allowed.
