roles/common: Tweak sshd_config to match NSA Suite B recommendations
NSA stopped recommending AES-128 in August, 2015...

Before: https://web.archive.org/web/20150403110658/https://www.nsa.gov/ia/programs/suiteb_cryptography/index.shtml
After: https://web.archive.org/web/20150815072948/https://www.nsa.gov/ia/programs/suiteb_cryptography/index.shtml

I don't see why we shouldn't follow suit; maybe they know something
we don't!

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*

For security and predictability clients should only get a reponse
if they request a hostname we are actually hosting.

If TLS is in use then this will use a self-signed snakeoil cert for
an HTTPS-enabled blank, default vhost.

roles/common: Specify default apt_mirror for fallback in sources.list template
New hosts often fail due to not having an apt_mirror, because there
isn't one defined for their group and their host_vars haven't over-
ridden it.

We want new hosts to deploy successfully, so let's just use a default
apt_mirror if there isn't one defined. Rather have a slow mirror than
a failed deployment. And in any case, Linode can download from KENET's
mirror at 10MB/sec. ;)

roles/nginx: Use Linode DNS servers for OCSP resolvers

Here is OpenDNS:

'always' is legal in nginx >= 1.7.5:
