Running with a user (like `matrix:matrix`) fails if Etherpad is enabled,
because `/matrix/etherpad` is owned by `matrix_etherpad_user_uid`/`matrix_etherpad_user_gid` (`5001:5001`).
The `matrix` user can't acccess the Etherpad directory for this reason
and Borgmatic fails when trying to make a backup.
There may be other things under `/matrix` which similarly use
non-`matrix:matrix` permissions.
Another workaround might have been to add `/matrix/etherpad` (and
potentially other things) to `matrix_backup_borg_location_exclude_patterns`, but:
- that means Etherpad won't be backed up - not great
- only excluding Etherpad may not be enough. There may be other files we
need to exclude as well
---
Running with `root` is still not enough though.
We need at least the `CAP_DAC_OVERRIDE` capability, or we won't be able to read the
`/etc/borgmatic.d/config.yaml` configuration file (owned by
`matrix:matrix` with `0640` permissions).
---
Additionally, it seems like the backup process tries to write to at least a few directories:
- `/root/.borgmatic`
- `/root/.ssh`
- `/root/.config`
> [Errno 30] Read-only file system: '/root/.borgmatic'
> Error while creating a backup.
> /etc/borgmatic.d/config.yaml: Error running configuration file
We either need to stop mounting the container filesystem as readonly
(remove `--read-only`) or to allow writing via a `tmpfs`.
I've gone the `tmpfs` route which seems to work.
In any case, the mounted source directories (`matrix_backup_borg_location_source_directories`)
are read-only regardless, so our actual source files are protected from unintentional changes.
Without this, it's a string and borg says:
> At 'hooks.postgresql_databases[INDEX_HERE].port': '5432' is not of type 'integer'
> /etc/borgmatic/config.yaml /etc/borgmatic.d /tmp/.config/borgmatic/config.yaml /tmp/.config/borgmatic.d: No valid configuration files found
.. and fails to do anything.
This role is usable on its own and it's not tied to Matrix, so
extracting it out into an independent role that we install via
ansible-galaxy makes sense.
This also fixes the confusion from the other day, where
`matrix_postgres_*` had to be renamed to `devture_postgres_*`
(unless it was about `matrix_postgres_backup_*`).
We now can safely say that ALL `matrix_postgres_*` variables need to be
renamed.

More details about the new key type can be found here:
https://eff-certbot.readthedocs.io/en/stable/using.html#rsa-and-ecdsa-keys
Existing RSA-based keys will continue to renew as RSA until manual
action is taken. Example from the documentation above:
> certbot renew --key-type ecdsa --cert-name example.com --force-renewal
In the future, we may add a command which does this automatically for
all domains.
* added dendrite captcha options
* added hcaptcha doc
* proper url
* Apply suggestions from code review

* Update main.yml
* renamed captcha vars to new naming scheme
* change vars to new format
* Rename back some incorrect renamed variables
These variables are either not just part of the `client_api` subsection,
or are not even part of that section at all. They shouldn't have been
renamed in baaef2ed616e2645550d9
* Fix up naming inconsistencies
Some of these variables had been renamed in one place,
but not in other places, so it couldn't have worked that way.
* Add validation/deprecation for renamed Dendrite variables
