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.
There was no need to add `synapse` to the list manually
and then add all other additional databases.
When the `synapse` database was the main database, this made sense.
Since a long time ago already, ALL databases are "additional" databases,
so the `synapse` database is part of that list.
We could additional add the main (`matrix`) database to this list,
but there's probably no point in backing that one up.
Tests were carried out like this:
- `virtualenv3 env`
- `./env/bin/pip install ansible==4.10.0 ansible-core==2.11.7`
- `./env/bin/ansible-playbook .....`
The lowest version of `ansible-core` available on PyPI right now is
2.11.0. That version has trouble with `ansible==4.0.0` though.
The errors we were hitting seemed to be resolved by others online by
using `ansible==4.10.0` instead, which has a minimum `ansible-core`
requirement of `2.11.7`, so that's what we went with.
Older versions of Ansible may work, but.. I'm having trouble
installing them and don't want to spend too much time on digging through
ancient versions and testing them out. People should just learn to run
up-to-date software.
