roles/php5-fpm: Disable always_populate_raw_post_data
Deprecated in PHP 5.6 and causes problems with Piwik. I'm not sure
if WordPress needs this, but I did find some references in its code
to $HTTP_RAW_POST_DATA.

roles/nginx: Add HSTS check to vhost template
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).

roles/nginx: Move HTTP Strict Transport Security toggle to vhosts
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.

roles/common: Add sysctl template for Debian hosts
Note: I've only tested this on a Debian container, and you can't
set these sysctls on containers (the host controls them). To make
matters worse, there is no fact to make ansible skip this on hosts
that are running in containers. For now I will just skip it on
hosts that are "virtualization" servers... even though we actually
do have KVM running on Debian on real hardware. *sigh*

We want new hosts to deploy successfully, so let's just use a default

a failed deployment. And in any case, Linode can download from KENET's
mirror at 10MB/sec. ;)

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

headers in the current block. In this case the FastCGI cache header

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.
