roles/nginx: Add $request_method to nginx fastcgi_cache_key 
nginx is caching HEAD requests, then when users come along and do
a GET request they get an HTTP 200 with no request body. It seems
setting fastcgi_request_methods to GET doesn't stop nginx from caching
HEADs, so for now just add the $request_method to the key.

Remove provisioning user management 
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.

Move Debian.yml vars to Ubuntu.yml 
I was using ansible_os_family to get settings for Debian-family
hosts, but this doesn't work so well when you have an apt_mirror
which is only Debian or Ubuntu, for example.

I don't have any Debian hosts here, but anyways, it's better this
way so I can be more flexible in the future.

Alan Orth 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".
