With this change, it should be possible for people to adjust the Docker
dependency from `docker.service` to something else (e.g. `pkg-ContainerManager-dockerd.service`),
or to completely eliminate it by setting `devture_systemd_docker_base_docker_service_name` to an empty string.

This makes it easier for people to use the playbook against a Synology DSM server.

Appservice Draupnir for All required Develop before the release of 1.87.0 to work at all in the playbook. Now that we have a release to pin to we will return to being pinned to a release. Especially as Draupnir 2.0.0 push is happening now in main. This will mean that Draupnir develop is expected to be much more unstable than usual for a bit so its important that we pin to a stable release. These releases are validated due to having been dogfooded ever since D4A was merged into the playbook.

* Draupnir for all Role

* Draupnir for all Documentation

* Pin D4A to Develop until D4A patches are in a release.

* Update D4A Docs to mention pros and cons of D4A mode compared to normal

* Change Documentation to mention a fixed simpler provisioning flow.

Use of /plain allows us to bypass the bugs encountered during the development of this role with clients attempting to escape our wildcards causing the grief that led to using curl.

This reworded commit does still explain you can automatically inject stuff into the room if you wanted to.

* Emphasise the State of D4A mode

* Link to Draupnir-for-all docs and tweak the docs some

* Link to Draupnir-for-all from Draupnir documentation page

* Announce Draupnir-for-all
