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*

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. ;)

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.
