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.

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!

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).

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.

For security and predictability clients should only get a reponse
if they request a hostname we are actually hosting.
If TLS is in use then this will use a self-signed snakeoil cert for
an HTTPS-enabled blank, default vhost.

A template is better than ansible's `apt_repository` module because
we can idempotently control the contents of the file based on vari-
ables.

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.

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.

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.

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.

Bypasses caching for logged in users (right now only for sessions
where the "wordpress_logged_in" cookie is set. Doubles the trans-
actions per second as measured by siege:

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.

Use "public" with "max-age" instead of Expires, as "max-age" is always
preferred if it's present. Note: setting "public" doesn't make the
resource "more cacheable", but it is just more explicit.
