Fixes#9490
This will break a couple of SyTest that are expecting failures to be added to the response of a federation /send, which obviously doesn't happen now that things are asynchronous.
Two drawbacks:
Currently there is no logic to handle any events left in the staging area after restart, and so they'll only be handled on the next incoming event in that room. That can be fixed separately.
We now only process one event per room at a time. This can be fixed up further down the line.
Implemented config option sso.update_profile_information to keep user's display name in sync with the SSO displayname.

We were repeatedly looking up a config option in a loop (using the
unclassed config style), which is expensive enough that it can cause
large CPU usage.
An accidental mis-ordering of operations during #6739 technically allowed an incoming knock event over federation in before checking it against any configured Third Party Access Rules modules.
This PR corrects that by performing the TPAR check *before* persisting the event.
This could cause a minor data leak if someone defined a non-restricted join rule
with an allow key or used a restricted join rule in an older room version, but this is
unlikely.
Additionally this starts adding unit tests to the spaces summary handler.
This PR adds a common configuration section for all modules (see docs). These modules are then loaded at startup by the homeserver. Modules register their hooks and web resources using the new `register_[...]_callbacks` and `register_web_resource` methods of the module API.
Fixes https://github.com/matrix-org/synapse/issues/10030.
We were expecting milliseconds where we should have provided a value in seconds.
The impact of this bug isn't too bad. The code is intended to count the number of remote servers that the homeserver can see and report that as a metric. This metric is supposed to run initially 1 second after server startup, and every 60s as well. Instead, it ran 1,000 seconds after server startup, and every 60s after startup.
This fix allows for the correct metrics to be collected immediately, as well as preventing a random collection 1,000s in the future after startup.
Dangerous actions means deactivating an account, modifying an account
password, or adding a 3PID.
Other actions (deleting devices, uploading keys) can re-use the same UI
auth session if ui_auth.session_timeout is configured.
* Trace event persistence
When we persist a batch of events, set the parent opentracing span to the that
from the request, so that we can trace all the way in.
* changelog
* When we force tracing, set a baggage item
... so that we can check again later.
* Link in both directions between persist_events spans
* Room version 7 for knocking.
* Stable prefixes and endpoints (both client and federation) for knocking.
* Removes the experimental configuration flag.
Add 'federation_ip_range_whitelist'. This allows backwards-compatibility, If 'federation_ip_range_blacklist' is set. Otherwise 'ip_range_whitelist' will be used for federation servers.

This is the first of two PRs which seek to address #8518. This first PR lays the groundwork by extending ResponseCache; a second PR (#10158) will update the SyncHandler to actually use it, and fix the bug.
The idea here is that we allow the callback given to ResponseCache.wrap to decide whether its result should be cached or not. We do that by (optionally) passing a ResponseCacheContext into it, which it can modify.

Bugfixes
--------
- Fix a bug which caused presence updates to stop working some time after a restart, when using a presence writer worker. Broke in v1.33.0. ([\#10149](https://github.com/matrix-org/synapse/issues/10149))
- Fix a bug when using federation sender worker where it would send out more presence updates than necessary, leading to high resource usage. Broke in v1.33.0. ([\#10163](https://github.com/matrix-org/synapse/issues/10163))
- Fix a bug where Synapse could send the same presence update to a remote twice. ([\#10165](https://github.com/matrix-org/synapse/issues/10165))

This is essentially an implementation of the proposal made at https://hackmd.io/@richvdh/BJYXQMQHO, though the details have ended up looking slightly different.
Spawned from missing messages we were seeing on `matrix.org` from a
federated Gtiter bridged room, https://gitlab.com/gitterHQ/webapp/-/issues/2770.
The underlying issue in Synapse is tracked by https://github.com/matrix-org/synapse/issues/10066
where the message and join event race and the message is `soft_failed` before the
`join` event reaches the remote federated server.
Less soft_failed events = better and usually this should only trigger for events
where people are doing bad things and trying to fuzz and fake everything.
