vars/Ubuntu.yml: Remove apt_mirror 
It's better to just use Ubuntu's defaults, and then override on a
per-host basis.

Alan Orth 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.

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".

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.

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.

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...
