* 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

Fixup for https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/3017
This reverts 1cd82cf068 and also multiplies results by `1024`
so as to pass bytes to Synapse, not KB (as done before).
1cd82cf068 was correctly documenting what we were doing (passing KB values),
but that's incorrect.
Synapse's Config Conventions
(https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#config-conventions)
are supposed to clear it up, but they don't currently state what happens when you pass a plain number (without a unit suffix).
Thankfully, the source code tells us:
bc1db16086/synapse/config/_base.py (L181-L206)
> If an integer is provided it is treated as bytes and is unchanged.
>
> String byte sizes can have a suffix of ...
> No suffix is understood as a plain byte count.
We were previously passing strings, but that has been improved in 3d73ec887a.
Regardless, non-suffixed values seem to be treated as bytes by Synapse,
so this patch changes the variables to use bytes.
Moreover, we're moving from `matrix_synapse_memtotal_kb` to
`matrix_synapse_cache_size_calculations_memtotal_bytes` as working with
the base unit everywhere is preferrable.
Here, we also introduce 2 new variables to allow for the caps to be
tweaked:
- `matrix_synapse_cache_size_calculations_max_cache_memory_usage_cap_bytes`
- `matrix_synapse_cache_size_calculations_target_cache_memory_usage_cap_bytes`
* Modify Synapse Cache Factor to use Auto Tune
Synapse has the ability to as it calls in its config auto tune caches.
This ability lets us set very high cache factors and then instead limit our resource use.
Defaults for this commit are 1/10th of what Element apparently runs for EMS stuff and matrix.org on Cache Factor and upstream documentation defaults for auto tune.
* Add vars to Synapse main.yml to control cache related config
This commit adds various cache related vars to main.yml for Synapse.
Some are auto tune and some are just adding explicit ways to control upstream vars.
* Updated Auto Tune figures
Autotuned figures have been bumped in consultation with other community members as to a reasonable level. Please note these defaults are more on the one of each workers side than they are on the monolith Side.
* Fix YML Error
The playbook is not happy with the previous state of this patch so this commit hopefully fixes it
* Add to_json to various Synapse tuning related configs
* Fix incorrect indication in homeserver.yaml.j2
* Minor cleanups
* Synapse Cache Autotuning Documentation
* Upgrade Synapse Cache Autotune to auto configure memory use
* Update Synapse Tuning docs to reflect automatic memory use configuration
* Fix Linting errors in synapses main.yml
* Rename variables for consistency (matrix_synapse_caches_autotuning_* -> matrix_synapse_cache_autotuning_*)
* Remove FIX ME comment about Synapse's `cache_autotuning`
`docs/maintenance-synapse.md` and `roles/custom/matrix-synapse/defaults/main.yml`
already contains documentation about these variables and the default values we set.
* Improve "Tuning caches and cache autotuning" documentation for Synapse
* Announce larger Synapse caches and cache auto-tuning

This changes the behavior of
`matrix_playbook_migration_matrix_nginx_proxy_uninstallation_enabled`
and is against what we initially described in the changelog entry,
but I've discovered some problems when the `matrix-nginx-proxy` service
and container remain running. They need to go.
Issues and Pull Requests were not migrated to the new
organization/repository, so `matrix-org/synapse/pull` and
`matrix-org/synapse/issues` references were kept as-is.
`matrix-org/synapse-s3-storage-provider` references were also kept,
as that module still continues living under the `matrix-org` organization.
This patch mainly aims to change documentation-related things, not actual
usage in full yet. For polish that, another more comprehensive patch is coming later.
