Subject: [PATCH 1/6] Add matrix-appservice-kakaotalk support

Adds support for: https://src.miscworks.net/fair/matrix-appservice-kakaotalk

This is pretty similar to
https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1977
which just appeared, but has mostly been done independently.

I've taken some inspiration and did some fixups based on that PR.
Thanks to https://github.com/hnarjis for taking the time to contribute!

Notable differences between this branch compared to that PR:

- better naming and documentation around the "configuration" variables
- no unnecessary (5 sec.) intentional delay when starting `matrix-appservice-kakaotalk-node.service`
- stores configuration in `config/`, not in `data/`
- passes configuration as read-only and starts the bridge with (`--no-update`) to ensure no changes are made to it
- starts containers more securely - with `matrix:matrix` user:group (not `root`) and
  reduced capabilities (`--cap-drop=ALL`)
- uses `tcp` for communication between the "node" and the appservice (simpler than sharing unix sockets)
- `registration.yaml` which is closer to the one generated by `matrix-appservice-kakaotalk` (no `de.sorunome.msc2409.push_ephemeral` stuff, etc.)
- `registration.yaml` which is more customizable (customizable bot username and prefix for puppets - see `matrix_appservice_kakaotalk_appservice_bot_username` and `matrix_appservice_kakaotalk_user_prefix`)
- less fragile and more extensible bridge permissions configuration via `matrix_appservice_kakaotalk_bridge_permissions`. Doing `{% if matrix_admin %}` in the bridge configuration sometimes causes syntax problems (I hit some myself) and is not ideal. Other bridges should be redone as well.
- configurable command prefix for the bridge, instead of hardcoding `!kt` (see `matrix_appservice_kakaotalk_command_prefix`)
- logging that is more consistent with the rest of the playbook (console / journald only, no logging to files), as well as configurable log level (via `matrix_appservice_kakaotalk_logging_level`)
- somewhat more detailed documentation (`docs/configuring-playbook-bridge-appservice-kakaotalk.md`)
- removed some dead code (data relocation tasks from `tasks/setup_install.yml`, as well as likely unnecessary SQLite -> Postgres migration)

+# Setting up Appservice Kakaotalk (optional)
+
+The playbook can install and configure [matrix-appservice-kakaotalk](https://src.miscworks.net/fair/matrix-appservice-kakaotalk) for you. `matrix-appservice-kakaotalk` is a bridge to [Kakaotalk](https://www.kakaocorp.com/page/service/service/KakaoTalk?lang=ENG) based on [node-kakao](https://github.com/storycraft/node-kakao) (now unmaintained) and some [mautrix-facebook](https://github.com/mautrix/facebook) code.
+
+See the project's [documentation](https://src.miscworks.net/fair/matrix-appservice-kakaotalk) to learn what it does and why it might be useful to you.
+
+## Installing
+
+To enable the bridge, add this to your `vars.yml` file:
+
+```yaml
+matrix_appservice_kakaotalk_enabled: true
+```
+
+You may optionally wish to add some [Additional configuration](#additional-configuration), or to [prepare for double-puppeting](#set-up-double-puppeting) before the initial installation.
+
+After adjusting your `vars.yml` file, re-run the playbook and restart all services: `ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start`
+
+To make use of the Kakaotalk bridge, see [Usage](#usage) below.
+
+
+### Additional configuration
+
+There are some additional things you may wish to configure about the bridge.
+
+Take a look at:
+
+- `roles/matrix-bridge-appservice-kakaotalk/defaults/main.yml` for some variables that you can customize via your `vars.yml` file
+- `roles/matrix-bridge-appservice-kakaotalk/templates/config.yaml.j2` for the bridge's default configuration. You can override settings using the `matrix_appservice_kakaotalk_configuration_extension_yaml` variable
+
+Here's some example configuration (which goes into your `vars.yml` file):
+```yaml
+# This configuration:
+# - enables encryption (it's off by default)
+# - grants some user on your homeserver 'admin' access to the bridge
+#   (note: the user specified in the `matrix_admin` (part of `roles/matrix-base/defaults/main.yml`) is made an admin by default)
+matrix_appservice_kakaotalk_configuration_extension_yaml: |
+  bridge:
+    permissions:
+      '@YOUR_USERNAME:{{ matrix_domain }}': admin
+
+    encryption:
+      allow: true
+      default: true
+```
+
+
+### Set up Double Puppeting
+
+If you'd like to use [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do), you have 2 ways of going about it.
+
+#### Method 1: automatically, by enabling Shared Secret Auth
+
+The bridge will automatically perform Double Puppeting if you enable [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) for this playbook.
+
+This is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.
+
+#### Method 2: manually, by asking each user to provide a working access token
+
+**Note**: This method for enabling Double Puppeting can be configured only after you've already set up bridging (see [Usage](#usage)).
+
+When using this method, **each user** that wishes to enable Double Puppeting needs to follow the following steps:
+
+- retrieve a Matrix access token for yourself. You can use the following command:
+
+```
+curl \
+--data '{"identifier": {"type": "m.id.user", "user": "YOUR_MATRIX_USERNAME" }, "password": "YOUR_MATRIX_PASSWORD", "type": "m.login.password", "device_id": "Appservice-Kakaotalk", "initial_device_display_name": "Appservice-Kakaotalk"}' \
+https://matrix.DOMAIN/_matrix/client/r0/login
+```
+
+- send the access token to the bot. Example: `login-matrix MATRIX_ACCESS_TOKEN_HERE`
+
+- make sure you don't log out the `Appservice-Kakaotalk` device some time in the future, as that would break the Double Puppeting feature
+
+
+## Usage
+
+Start a chat with `@kakaotalkbot:YOUR_DOMAIN` (where `YOUR_DOMAIN` is your base domain, not the `matrix.` domain).
+
+Send `login --save EMAIL_OR_PHONE_NUMBER` to the bridge bot to enable bridging for your Kakaotalk account. The `--save` flag may be omitted, if you'd rather not save your password.
+
+After successfully enabling bridging, you may wish to [set up Double Puppeting](#set-up-double-puppeting), if you haven't already done so.

Subject: [PATCH 4/6] Use kakaotalk_ as the puppet prefix

This is what upstream uses and also what
https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1977
used.

Initially, I wanted to make the prefix more unique, in case another
Kakaotalk bridge comes along, but.. it's probably on the new bridge to
come up with a unique puppet prefix, not on us now to override upstream
decisions.

+## matrix-appservice-kakaotalk support
+
+The playbook now supports bridging to [Kakaotalk](https://www.kakaocorp.com/page/service/service/KakaoTalk?lang=ENG) via [matrix-appservice-kakaotalk](https://src.miscworks.net/fair/matrix-appservice-kakaotalk) - a bridge based on [node-kakao](https://github.com/storycraft/node-kakao) (now unmaintained) and some [mautrix-facebook](https://github.com/mautrix/facebook) code. Thanks to [hnarjis](https://github.com/hnarjis) for helping us add support for this!
+
+See our [Setting up Appservice Kakaotalk bridging](docs/configuring-playbook-bridge-appservice-kakaotalk.md) documentation to get started.
