151fb29687 roles/nginx: Add blank vhost 
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. ;)

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.

setting fastcgi_request_methods to GET doesn't stop nginx from caching

It's just too tricky to manage this. Ubuntu / RedHat preseeds and
kickstarts can create the user and add it to groups, but only when
we control the initial boot environment (ie not on Linode, Digital
Ocean, etc), so let's just say we assume this user exists and can
get root with sudo by the some we are running ansible on it.

0f5b088c08 roles/common: Add createhome:yes to provisioning user task 
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: 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.

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.

Prevailing wisdom is actually that this *can* help virtual hosts,
especially when the VM guest has multiple CPUs.

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...
