roles/common: Update apt in firewall task
Otherwise the buster-backports source might not be available, as
the nightly security upates use a different apt sources.list.

roles/nginx: Fix hardcoded "stretch" release in sources
This was causing the stretch version to get installed on buster, w-
hich led to the cipher suite and ssl protocol support to behave st-
rangeley.

roles/common: Increase ssh MaxAuthTries from 3 to 4
If a user has RSA, ECDSA, and ED25519 private keys present on their
system then the ssh client will offer all of these to the server
and they may not get a chance to try password auth before it fails.

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/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/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.

Vanilla Ubuntu (and Debian actually) defaults to using the official

Also, for what it's worth, Ubuntu mirrors didn't always sync these

also it kinda makes sense to get security updates from the official
source than a mirror (in case of delay or errors).

d1ba60e15d Use version_compare to test for Ubuntu 18.04 "bionic"

9f3ab01d48 roles/php-fpm: Use include instead of import for tasks
These tasks are conditional and mutually exclusive due to the "when"
clause. Using import_tasks means that these are imported before the
playbook execution and then skipped during evaluation of the test.

It makes sense in this case to use include_tasks so that the tasks
are only imported during playbook execution if the condition is met.
