Take an opinionated stance on HTTPS and assume that hosts are using
HTTPS for all vhosts. This can either be via custom TLS cert/key
pairs defined in the host's variables (could even be self-signed
certificates on dev boxes) or via Let's Encrypt.
Hosts can specify use_letsencrypt: 'yes' in their host_vars. For
now this assumes that the certificates already exist (ie, you have
to manually run Let's Encrypt first to register/create the certs).
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.

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.

Set `use_snakeoil_cert: 'yes'` in host_vars. This is good for dev
hosts where we don't have real domains or real certs. But everything
should have TLS.

For now I generated the certs manually, but in the future the play-
book should run the letsencrypt-auto client for us!

This is really a per-site setting, so it doesn't make sense to have
a role default. Anyways, HSTS is kinda tricky and potentially dang-
erous, so unless a vhost explicitly sets it to "yes" we shouldn't
enable it.
Note: also switch from using a boolean to using a string; it is st-
ill declarative, but at least now I don't have to guess whether it
is being treated as a bool or not.

I was only setting it on the PHP block, which is for all dynamic
requests (ie pages from WordPress), but it should also be the same
for all static files not served from that block.

I was attempting to make the config easier to use in test environments
where the key is self-signed, but meh, I rarely do that and I think
this logic doesn't actually work.

Reduces round trip time for clients. Note: I am using a certificate
chain in the `ssl_certificate' directive, so as I understand it, I
don't need to use an explicit trusted intermediate + root CA cert
with the `ssl_trusted_certificate' option. See the nginx docs for
more[0]. Addresses GitHub Issue #5.
Seems to be working, test with:
$ openssl s_client -connect mjanja.ch:443 -servername mjanja.ch -tls1 -tlsextdebug -status
Look for "OCSP Response" with "Cert Status: good".

Default is 5 minutes, but it seems like unless you're a high-traff-
ic site, there's no need to expire sessions so quickly. Also, the
istlsfastyet.com configs are using 24 hours, so surely we can.

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.
