alertmanager: remove GitLab webhook integration

See merge request !578

Nobody uses this for alert management and we also have Grafana showing
the alerts now.

Removing just the list of vaulted var files triggers a schema violation.

Addresses the following ansible-lint warning:

risky-file-permissions: File permissions unset or incorrect.
roles/install_arch/tasks/main.yml:50

As reported by ansible-lint 6.2.1:

schema: [{'PYTHONPATH': '.'}] is not of type 'object' (schema[tasks])
roles/aurweb/tasks/main.yml:1

schema: [{'SHELL': '/bin/bash'}] is not of type 'object' (schema[tasks])
roles/dbscripts/tasks/main.yml:1

The "line-length" and "braces" rules are now named "yaml[line-length]"
and "yaml[braces]" respectively.

With a delay of 30 seconds. Reduce the sleep hack in pantalaimon from 30
to 10 seconds. Hopefully this is going to bring it up reliably.

dovecot: enable the duplicate Sieve extension

See merge request !576

Useful for preventing message duplication when the recipient is also
part of an alias included in Cc (e.g. foutrelis@ + infrastructure@).

borg_client: run compact after pruning on borg 1.2

See merge request !577

Only doing this on the Hetzner storage box for now; waiting for
rsync.net to upgrade to borg 1.2 so we can enable it there too.

Fixes: 0b87cbfd ("mta_sts: Switch to enforce mode and bump max_age to 30 days")

Ansible side of commit 5007c1a8 ("tf-stage1: allow setting the NS
TTL of geo domains"); both values need to match so our geo nameservers
report the same TTL as that returned by the parent zone's nameservers.

When adding a new geo domain or doing other testing, we would want to
use a low TTL to allow for making quick changes to the configuration.

Checking the SMTP TLS reports, the last failure was 2021-12-10/11 from
Mail.ru and 2021-08-28/29 from Google.

Bumping the max_age to 30 days as the RFC states: "To mitigate the risks
of attacks at policy refresh time, it is expected that this value
typically be in the range of weeks or greater."[1].

It is run as part of the nntp runner now[1].

Setup mailman3 server

See merge request !437

The server has been reimaged to be sure the playbook and roles work as
intended.

arch-announce
arch-devops-private
arch-events
arch-wiki-admins

mailman-web has been packaged in the community repo and it uses
different paths than my homebrewed PKGBUILD.

We want to migrate to mailman3 as mailman2 is basically unmaintained and
requires Python 2 which is EOL.

Because the mailman and mailman3 packages conflict and we don't want to
perform a big bang migration, mailman3 must be deployed on a separate
server. mailman-web (mailman3's web interface) hasn't been packaged yet,
so for now we are using my homebrewed PKGBUILD[1].

Ref #59

Fixes: afb582b1 ("geomirror: extract acme dns challenge into new role")

debuginfod: let nginx compress octet-stream responses

See merge request !573

Using the fastest gzip compression level to avoid burning too much CPU.

Implement generalized support for geo domains

See merge request !574

The intention is to use this config for other domains besides a mirror.

- add the new role to redirect.archlinux.org
- release mirror.pkgbuild.com of all DNS duties

Kevin is MIA, so add my key, so we can do releases.

Provision server for buildbot POC

See merge request !571

Foxboron wants some infra for a buildbot POC, so let's give it to him!

The server has been configured with the common and firewalld role.
