roles/nginx: Disable SSL session tickets
Session tickets increase performance, but decrease security, so
let's just turn them off.  See the following posts:

roles/nginx: Set nginx SSL session timeout to 24 hours
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.

be6c76a2af roles/nginx: Set nginx SSL buffer size to 1400
istlsfastyet.com recommends setting the buffer size to 1400 so it
can fit into a single MTU.  nginx default is 16k!

roles/nginx: Adjust Cache-Control headers
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.

Downgrade TLS configuration to Mozilla's "intermediate" spec
From looking at the list of clients who would be allowed to connect
when using the "modern" spec, I think I'd be doing more harm than
good to use that config right now...

roles/nginx: Update TLS vhost task for Ansible > 1.7.1
Seems there is some YAML sublety that causes this syntax to insert

are a workaround, see GitHub issues:

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.
