roles/common: Use one task to remove Ubuntu packages
I had previously been removing some packages for security reasons,
then removing others because they were annoying, and yet *others*
because they were annoying on newer Ubuntus only. It is easier to
just unify these tasks and remove them all in one go.

On older Ubuntus where some packages don't exist the task will just
succeed because the package is absent anyways.

roles/common: Use a persistent systemd journal
The default systemd journal configuration on CentOS 7 and Ubuntu
16.04 does not keep journal logs for multiple boots. This limits
the usefulness of the journal entirely (for example, try to see
sshd logs from even two or three months ago!).

Changing the storage to "persistent" makes systemd keep the logs
on disk in /var/log/journal for up to 2% of the partition size.

roles/common: Limit number of SSH authentication attempts
The default in later OpenSSH is 6, which seems too high. If you can't
get your password correct after 3 tries then I think you need help.

Eventually I'd like an easy way to enable blocking of repeated login
attempts at the firewall level. I think it's possible in firewalld.

roles/php-fpm: Use set_fact to set packages
Instead of looping over a list of items to install, we can actually
just give a list directly to the apt module. This allows the module
to install all packages in one transaction, which is faster as well
as slightly safer for some dependency resolution scenarios.

roles/php-fpm: Remove "packages" tag
This tag is no longer reachable after switching to the new dynamic
includes in Ansible 2.4 and 2.5. Anyways, I've been questioning my
decision to add the "packages" tag to any task that uses the apt
module.

roles/php-fpm: Use blocks to tag children of dynamic tasks
When using dynamic includes, child tasks do not inherit tags from their
parents. You must tag the parent and each child task separately, or use
a block to group children and then apply a tag to a block.

roles/nginx: Move WordPress tasks to separate file
Because of the shift from static imports to dynamic includes these
tags will never be reached unless they have their own task that is
tagged at the top-level (dynamic includes don't pass their tags to
their children).

roles/nginx: Use dynamic includes for Let's Encrypt
As of Ansible 2.4 and 2.5 the behavior for importing tasks has changed
to introduce the notion of static imports and dynamic includes. If the
tasks doing the import is using variable interpolation or conditionals
then the task should be dynamic. This results in quicker playbook runs
due to less importing of unneccessary tasks.

One side effect of this is that child tasks of dynamic includes do not
inherit their parents' tags so you must tag them explicitly or a block.

Also, I had to move the letsencrypt tasks to the main task file so the
tags were available (due to dynamic tasks not inheriting tags).

roles/nginx: Use dynamic include_tasks for Let's Encrypt
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/nginx: Separate Debian 9 "stretch" Let's Encrypt deps
Instead of iterating over fifteen packages with a loop that does fifteen
separate apt transactions, it is better to give the apt module a list so
it can install them all in one transaction. This is both quicker and te-
chnically more safe for dependency resolution.

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.

roles/common: Always use security.ubuntu.com
Vanilla Ubuntu (and Debian actually) defaults to using the official
mirror for security updates rather than country or regional mirrors.

Also, for what it's worth, Ubuntu mirrors didn't always sync these
security archives. I'd prefer to stay closer to vanilla Ubuntu but
also it kinda makes sense to get security updates from the official
source than a mirror (in case of delay or errors).

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.
