roles/nginx: Harden security headers 
Always add security headers, not just for successful HTTP response
codes. See the nginx `add_header` docs.

Revert "roles/nginx: Only run Let's Encrypt checks once a day" 
This reverts commit a38d822fad.

The docs definitely recommend twice a day. From a note on certbot's
installation page:

> if you're setting up a cron or systemd job, we recommend running
> it twice per day (it won't do anything until your certificates
> are due for renewal or revoked, but running it regularly would
> give your site a chance of staying online in case a Let's
> Encrypt-initiated revocation happened for some reason). Please
> select a random minute within the hour for your renewal tasks.

roles/nginx: Only run Let's Encrypt checks once a day 
I can't remember where I had seen it recommended to be twice a day,
but it seems overkill.

roles/nginx: Rework Let's Encrypt stuff 
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.

roles/nginx: Turn on tcp_nopush in nginx.conf 
It seems tcp_nopush is meant to be used with sendfile in newer
versions of nginx.

See: https://github.com/h5bp/server-configs-nginx/blob/master/nginx.conf
See: https://t37.net/nginx-optimization-understanding-sendfile-tcp_nodelay-and-tcp_nopush.html

roles/nginx: Set gzip_comp_level to 6

roles/nginx: Add $request_method to nginx fastcgi_cache_key 
nginx is caching HEAD requests, then when users come along and do
a GET request they get an HTTP 200 with no request body. It seems
setting fastcgi_request_methods to GET doesn't stop nginx from caching
HEADs, so for now just add the $request_method to the key.

roles/nginx: Add fastcgi caching 
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:

    $ siege -d1 -t1M -c50 https://mjanja.ch
