This also deprecates the somehwat disconnected docs github-mirror.md and new-gitlab.project.md

The fingerprints for the RSA and ECDSA key were swapped, fixed them.

It was Debian previously.

AURweb's rendercomment script uses python's libgit2 bindings which error
out when it can't read /home/aur/.git due to ProtectHome=true, instead
use ProtectHome=tmpfs.

This runner, as opposed to secure-runner1.archlinux.org, doesn't have any virtual machine capabilities and should be preferred for projects that don't need such capabilities.

We were seeing load spikes that pegged the server at 200% before.

This will ensure a smaller base image.

Apparently before if we ran a packer build to generate the arch base image, the problem was that it wouldn't pick up the fact that the machine was an hcloud server as that would only be checked after the first boot due to an ordering issue.
Now we manually make sure that packer builds (which are always on hcloud anyway) will always have the hcloud-init files installed properly.

Added the new ssh host keys fingerprints to the config.

After some consideration, we are going to start with a smaller server size
for the AUR and increase if necessary.

Since the AUR is high email traffic, apply the same rule as for luna,
and add the sasl_username for aur to the no limits list.

When installing the units, systemd was ignoring the Type of the unit
due to the capital O. Change it for the proper type.

Added the missing host_vars file for aur.archlinux.org and changed the README
to reflect it's move.

For security reasons, switch to using a socket for memcached on aurweb.

Added RandomizedDelaySec to make the aurweb-git.service to start on
a different time than the borg backup, so the machine does not hammered
by both running at the same time.

Added the borg tag again, since it's useful for running borg related
tasks.

Removed tags from playbooks, since they are auto-generated and also
synced the aur.archlinux.org playbook with aur-dev.archlinux.org one.

Added the server for the aur.archlinux.org migration. Used a CPX31
server, since AUR requires a bit more resources.

Added python-alembic to the package list and also running initdb.py for creating
the tables when the database is created and alembic update when there's changes to
the code.

Change the URL's of the aurweb project and the tu-bylaws project to point to
gitlab instead of git.archlinux.org.

The wip/aur branch was not checked for linting issues. Some of them were fixed,
but, particularly the git commands for setting the AUR repo, were skipped, because
the git module does not necessarily cover all the needs. Might be worth taking a look
about it on the future.

Since we are using Include, remove the sshd_config file.

Added support for the aurweb role to the new openssh include mechanism,
that's baked into our sshd role.

Added the uwsgi_modifier1 option to nginx as described on [0] and also
change the chmod option on the socket to allow nginx to connect to it.

Add the aur-dev changes to the aur playbook.

Add memcached to the playbook and also change the php extensions to use memcached.
Removed the apcu options from defatuls and added memcached settings. Added the php-memcached
packages to the list of needed packages and also remove the apcu tasks. Added the memcached
systemd unit file and enable and start it from the tasks.

Since git is installed on a separate step, remove it from the main list.

The original aur playbook file was missing a lot of the roles that were
added for the aur-dev playbook. Add them and renamed the file too.

Added a smartgit_socket option to the defaults. Reworked the tasks package
installation to look cleaner and also separated the cgit and git package installations
so we can trigger uwsgi reloads on updates. Changed the tubylaws repo update variable
to trigger the bylaws changes only when the tubylaws repository change, not the aurweb
one. Added tasks to install the apcu configuration, cgit uwsgi ini file, cgit rc file and
smartgit uwsgi ini file. Trigger an uwsgi reload in case the cgit-aurweb or git packages
change. Also added a few missing options to the aurweb configuration file. Rework the nginx
configuration file to use the cgit and smartgit uwsgi services.

Use the cgit_socket variable on the uwsgi template for cgit.
