roles/common: Remove unused sshd_config templates 
We're not supporting Ubuntu 14.04 or 15.04 anymore so we don't need
these templates.

roles/common: Use command module instead of shell 
You should only use the "shell" module when you need shell functions
like flow control and redirects. Also, the "command" module is safer
because it is not affected by the user's environment.

Alan Orth 0a92f3ae8f roles/common: Use systemd module instead of "service" 
This was new in Ansible 2.2 but I didn't notice until now. All of our

Revert "Import OS-specific vars in tasks instead of play" 
This reverts commit e30e4d4b1e.

I suspect this was a side effect of using Python 3 rather than an
issue in Ansible 2.4.0.0.

Revert "roles/common: Use static imports for tasks" 
This reverts commit 5147f4029b.

I think this was a side effect of using Python 3, not a regression in
Ansible 2.4.0.0.

roles/common: Use static imports for tasks 
Something seems to have happened as of Ansible 2.4.0.0 where this no
longer works. I suspect it is related to the major changes to static
and dynamic imports that landed around this same time.

In practice this achieves the same function, but without the "magic"
ability to use one task for different operating systems.

Adjust playbooks for Ansible 2.4 import changes 
Ansible 2.4 changes the way includes work. Now you have to use "import"
for playbooks and tasks that are static, and "include" for those that
are dynamic (ie, those that use variables, loops, etc).

Use Ansible's version_compare instead of doing math on strings 
I'm surprised this worked all these years actually. Since Ansible
version 1.6 it has been possible to use the version_compare filter
instead of doing math logic on strings.

Alan Orth 8851f8f631 Revert "Only update packages indexes if the cache is 1 hour old" 
This reverts commit 201165cff6.

Turns out this actually breaks initial deployments, because the
cache gets updated in the first task, then you add sources for
nginx and mariadb, but it doesn't update the indexes because the
cache is < 3600 seconds old, so you end up getting the distro's
versions of nginx and mariadb.

Alan Orth 201165cff6
Only update packages indexes if the cache is 1 hour old 
I have added cache_valid_time=3600 for the first task in each
tag that could be possibly running apt-related commands. For ex,
the "nginx" tag is also in the "packages" tag, but sometimes you
run the nginx tag by itself (perhaps repeatadely), so you'd want
to limit the update unless the cache was 1 hour old

roles/common: Use service module to enable systemd NTP client instead of timedatectl 
The `timedatectl set-ntp on` command is actually just enabling the

module.

roles/common: Remove 128-bit Ciphers and MACs from sshd_config 
I had removed them from Debian 8 and Ubuntu 14.04 configs last year
when the NSA's Suite B crypto guidelines dropped 128-bit algorithms
but those changes didn't make it to my new Ubuntu 16.04 config.

It is probably overkill and paranoid, but this server is mine, so I
can make those decisions (and I only connect from modern clients).

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.
