roles/common: Use dynamic include_tasks for firewall
Use dynamic includes instead of static imports when you are running
tasks conditionally or using variable interpolation. The down side
is that you need to then tag the parent task as well as all child
tasks, as tags only apply to children of statically imported tasks.

roles/common: Use dynamic include_tasks for packages
Basically, when using conditionals or variables in your tasks you should
use include_tasks instead of import_tasks. The down side is that you now
need to tag all included tasks individually or with a block, unlike when
using static imports (tags are applied to all imported child tasks).

I would actually like to reduce this task to a single one that uses the
host's ansible_distribution variable, but Ansible 2.5.1 currently gives
the following error: ansible_distribution is undefined.

Import OS-specific vars from task in common role
We stopped being able to do dynamic includes from the playbooks around
Ansible 2.4.0.0 if I recall correctly. Instead we can create a task to
include the variables and make it always run by using the special tag.

For now the Debian and Ubuntu vars files are the same, but I will keep
them separate so that it is more flexible in the future.

Update with_items loops to use new-ish "loop" keyword
Ansible 2.4 and 2.5 are moving away from specialized loop functions
and the old syntax will eventually be deprecated and removed. I did
not change the with_fileglob loops because I'm not sure about their
syntax yet.

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"

are dynamic (ie, those that use variables, loops, etc).

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.

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: 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*

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.
