roles/common: Update list of abusive IPv4 addresses
This comes from the AbuseIPDB with a confidence level of 95%. I use
the following command to download and sort the IPs:

$ curl -G https://api.abuseipdb.com/api/v2/blacklist -d confidenceMinimum=95 -H "Key: $ABUSEIPDB_API_KEY" -H "Accept: text/plain" | sort > /tmp/ips.txt

Then I add the XML formatting to the file and run it through tidy.

roles/common: Relax SSH rate limit in firewalld
Now that I'm blocking ~10,000 malicious IPs from AbuseIPDB I feel
more comfortable using a more relaxed rate limit for SSH. A limit
of 12 per minute is about one every five seconds.

roles/common: Update list of abusive IPv4 addresses
I updated the list with a few dozen more hosts that we brute forcing
SSH but failed to even negotiate a connection because they are using
old ciphers. I will still block them because they attempted 100+ co-
nnections.

roles/common: Add ipsets of abusive IPs to firewalld
This uses the ipsets feature of the Linux kernel to create lists of
IPs (though could be MACs, IP:port, etc) that we can block via the
existing firewalld zone we are already using. In my testing it works
on CentOS 7, Ubuntu 16.04, and Ubuntu 18.04.

The list of abusive IPs currently comes from HPC's systemd journal,
where I filtered for hosts that had attempted and failed to log in
over 100 times. The list is formatted with tidy, for example:

    $ tidy -xml -iq -m -w 0 roles/common/files/abusers-ipv4.xml

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

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/nginx: Separate Ubuntu 16.04 "Xenial" 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 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.

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).

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.

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.

roles/nginx: Make sure to set HSTS headers on WordPress static files
I realized the other day that due to complex logic in the location
blocks, various WordPress static files like images and stylesheets
didn't get the HTTP Strict Transport Security header set. We need
to include it on each level where we are setting headers, because
nginx overwrites headers if you set them again in a child block.

roles/nginx: Decrease gzip_min_length from 860 to 256
There was some knowledge floating around that 860 bytes was the
optimal size, I think it was from an Akamai engineer or something,
but the HTML 5 Boilerplate server configs use 256 bytes, and I
actually have HTML content that is less than 860 bytes, so I guess
I could benefit from compressing it. gzip compression is costly
for the compression side, but very quick for the client, so this
is a good thing.

After performing some tests[0] again I see that level 5 produces
the most acceptable results for my site currently. Others[1] are
using the same, so I'll gladly accept a little less CPU load for
a tradeoff of a few bits of file size.

Set use_letsencrypt to true for nginx role
The variable name is misleading as this really does is install the
certbot client and its dependencies, and we generally want this to
always happen. If a host doesn't want it, they can override it in
their host vars.

Perhaps I should rename this variable to "bootstrap_letsencrypt" or
something so it is more accurate.

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.

I have added cache_valid_time=3600 for the first task in each

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

The docs definitely recommend twice a day. From a note on certbot's
installation page:

> if you're setting up a cron or systemd job, we recommend running
> it twice per day (it won't do anything until your certificates
> are due for renewal or revoked, but running it regularly would
> give your site a chance of staying online in case a Let's
> Encrypt-initiated revocation happened for some reason). Please
> select a random minute within the hour for your renewal tasks.
