roles/nginx: Use template for nginx repo
A template is better than ansible's `apt_repository` module because
we can idempotently control the contents of the file based on vari-
ables.

roles/nginx: Adjust HSTS headers for https block of vhost template
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.

roles/nginx: Use Linode DNS servers for OCSP resolvers
I didn't realize Linode had DNS resolvers, but they are much closer
than anything else (obviously).

Here is OpenDNS:

    # mtr --report 208.67.222.222
    Start: Sun Mar 22 15:31:50 2015
    HOST: mjanja                    Loss%   Snt   Last   Avg  Best  Wrst StDev
      1.|-- router1-lon.linode.com     0.0%    10    0.5   0.9   0.5   3.4   0.7
      2.|-- 212.111.33.233             0.0%    10    1.4   1.4   1.2   1.9   0.0
      3.|-- 217.20.44.194              0.0%    10    0.7   0.8   0.7   1.2   0.0

      5.|-- resolver1.opendns.com      0.0%    10    1.0   0.9   0.8   1.0   0.0

And here is Linode's:

    # mtr --report 109.74.192.20
    Start: Sun Mar 22 15:32:30 2015
    HOST: mjanja                    Loss%   Snt   Last   Avg  Best  Wrst StDev

ae8937eb96 roles/nginx: Just enable OCSP
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.

roles/nginx: Add extra-security headers to PHP block
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.

04e453df51 Revert "roles/nginx: Correct HSTS header in https template"
This reverts commit 5c7404d228.

'always' is legal in nginx >= 1.7.5:

If the always parameter is specified (1.7.5), the header field will be added regardless of the response code.

roles/nginx: Correct HSTS header in https template
Apparently the "always" syntax isn't used anymore (ever?), not sure
where I got it from but this definitely causes HSTS to not work.

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: 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.

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.
