Make Facebook bridge configuration playbook-managed 

Related to #193, but for the Facebook bridge.
(other bridges can be changed to do the same later).

This patch makes the bridge configuration entirely managed by the
Ansible playbook. The bridge's `config.yaml` and `registration.yaml`
configuration files are regenerated every time the playbook runs.

This allows us to apply updates to those files and to avoid
people having to manage the configuration files manually on the server.

-------------------------------------------------------------

A deficiency of the current approach to dumping YAML configuration in
`config.yaml` is that we strip all comments from it.
Later on, when the bridge actually starts, it will load and redump
(this time with comments), which will make the `config.yaml` file
change.

Subsequent playbook runs will report "changed" for the
"Ensure mautrix-facebook config.yaml installed" task, which is a little
strange.

We might wish to improve this in the future, if possible.

Still, it's better to have a (usually) somewhat meaningless "changed"
task than to what we had -- never rebuilding the configuration.

# 2019-06-07
## (BC Break) Facebook bridge configuration is now entirely managed by the playbook
Until now, configuration files for the [Facebook bridge](docs/configuring-playbook-bridge-mautrix-facebook.md) were created by the playbook initially, but never modified later on.
From now on, the playbook will keep those configuration in sync for you.
This means that if you were making manual changes to the `/matrix/mautrix-facebook/config.yaml` or `/matrix/mautrix-facebook/registration.yaml` configuration files, those would be lost the next time you run the playbook.
You need to migrate your manual changes over to the new `matrix_mautrix_facebook_configuration_extension_yaml` variable, so that the playbook would apply them for you.
# 2019-05-25
## Support for exposing container ports publicly (not just to the host)
