This likely breaks QR code login for Synapse-worker setups.

This likely breaks QR code login for non-worker Synapse setups.

See https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3749

This merely hooks the playbook to the Traefik role's compression
middleware configuration (`traefik_config_http_middlewares_compression_*`)

The Traefik role enables the `compression` middleware by default.

Actual usage will land in a future commit.

gzipping certain responses is known to cause problems with QR code logins.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3749

Gzipping at the synapse-reverse-proxy-companion level and not at the
level of the outer-most reverse-proxy (Traefik) also sounds non-ideal.

This change only affects setups powered by Synapse workers.

Non-worker setups (and setups powered by other homeservers) were not
having their requests go through synapse-reverse-proxy-companion anyway,
so this change does not affect them.

Future patches may enable response compression support at the Traefik level for
all setups.

People who wish to disable this and keep their `/.well-known/matrix/client` file tidier
can do it via:

```yml
matrix_static_files_file_matrix_client_property_cc_etke_synapse_admin_enabled: false
```

Since a casual user might want to try another homeserver than Synapse without thinking about its consequence, it is important to clarify that it is not possible to switch homeservers once specified.
