Need to make sure the user gets created on a fresh install, like on
Amazon EC2 or OpenStack images where the first user is `ubuntu' and
you can't assume `provisioning' is already created.

6ccfdb99fa roles/nginx: Enable OCSP stapling 
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".

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.

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

when using the "modern" spec, I think I'd be doing more harm than
good to use that config right now...

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.
