This:
- brings consistency - no more mixing `_name_prefix` and `_registry_prefix`
- adds extensibility - a future patch will allow reconfiguring all registry prefixes for all roles in the playbook
We still have `_docker_` vs `_container_` inconsistencies.
These may be worked on later.
We used to pass the shared secret for double-puppeting via a
`login_shared_secret` parameter, which doesn't seem to exist anymore.
The proper way to do it is via `login_shared_secret_map`.
The comments for `login_shared_secret_map` seem to indicate that it's
only usable with the shared-secret-auth password provider.
However, this bridge is based on mautrix-python (`>=0.20.5,<0.21`) as
per its `requirements.txt`
Support for double-puppeting via arbitrary access tokens landed in
mautrix-python 0.20.1 (6f25b62e80/CHANGELOG.md (L44-L53)),
so it should be possible to use appservice double-puppet.

A bunch of other parameters seem to have moved around as well.
This patch introduces some new Ansible variables for controlling
additional settings related to encryption, etc.
