There are a few improvements over the experimental support:
- authorisation of Synapse <-> MAS requests is simplified, with a single
shared secret, removing the need for provisioning a client on the MAS
side
- the tests actually spawn a real server, allowing us to test the rust
introspection layer
- we now check that the device advertised in introspection actually
exist, making it so that when a user logs out, the tokens are
immediately invalidated, even if the cache doesn't expire
- it doesn't rely on discovery anymore, rather on a static endpoint
base. This means users don't have to override the introspection endpoint
to avoid internet roundtrips
- it doesn't depend on `authlib` anymore, as we simplified a lot the
calls done from Synapse to MAS
We still have to update the MAS documentation about the Synapse setup,
but that can be done later.

Fix https://github.com/element-hq/synapse/issues/18735
In https://github.com/element-hq/synapse/pull/18670, we updated
`run_as_background_process` to add a `server_name` argument. Because
this function is directly exported from the Synapse module API, this is
a breaking change to any downstream Synapse modules that use
`run_as_background_process`.
This PR shims and deprecates the existing
`run_as_background_process(...)` for modules by providing a stub
`server_name` value and introduces a new
`ModuleApi.run_as_background_process(...)` that covers the `server_name`
logic automagically.
Bulk refactor `Gauge` metrics to be homeserver-scoped. We also add lints
to make sure that new `Gauge` metrics don't sneak in without using the
`server_name` label (`SERVER_NAME_LABEL`).
Part of https://github.com/element-hq/synapse/issues/18592
### Testing strategy
1. Add the `metrics` listener in your `homeserver.yaml`
```yaml
listeners:
# This is just showing how to configure metrics either way
#
# `http` `metrics` resource
- port: 9322
type: http
bind_addresses: ['127.0.0.1']
resources:
- names: [metrics]
compress: false
# `metrics` listener
- port: 9323
type: metrics
bind_addresses: ['127.0.0.1']
```
1. Start the homeserver: `poetry run synapse_homeserver --config-path
homeserver.yaml`
1. Fetch `http://localhost:9322/_synapse/metrics` and/or
`http://localhost:9323/metrics`
1. Observe response includes the TODO metrics with the `server_name`
label

Default values will be 1 room per minute, with a burst count of 10.
It's hard to imagine most users will be affected by this default rate,
but it's intentionally non-invasive in case of bots or other users that
need to create rooms at a large rate.
Server admins might want to down-tune this on their deployments.

Best reviewed commit by commit.
With the new dedicated MAS API
(https://github.com/element-hq/synapse/pull/18520), it's possible that
deactivation starts off the main process, which was not possible because
of a few calls.
I basically looked at everything that the deactivation handler was
doing, reviewed whether it could run on workers or not, and find a
workaround when possible

The main goal of this PR is to handle device list changes onto multiple
writers, off the main process, so that we can have logins happening
whilst Synapse is rolling-restarting.
This is quite an intrusive change, so I would advise to review this
commit by commit; I tried to keep the history as clean as possible.
There are a few things to consider:
- the `device_list_key` in stream tokens becomes a
`MultiWriterStreamToken`, which has a few implications in sync and on
the storage layer
- we had a split between `DeviceHandler` and `DeviceWorkerHandler` for
master vs. worker process. I've kept this split, but making it rather
writer vs. non-writer worker, using method overrides for doing
replication calls when needed
- there are a few operations that need to happen on a single worker at a
time. Instead of using cross-worker locks, for now I made them run on
the first writer on the list

Another config option on my quest to a `*_path` variant for every
secret. Adds the config options `recaptcha_private_key_path` and
`recaptcha_public_key_path`. Tests and docs are included.
A public key is of course no secret, but it is closely related to the
private key, so it’s still useful to have a `*_path` variant for it.
You can now configure how much media can be uploaded by a user in a
given time period.
Note the first commit here is a refactor of create/upload content
function
This PR adds an additional `room_config` argument to the
`user_may_create_room` spam checker module API callback.
It will continue to work with implementations of `user_may_create_room`
that do not expect the additional parameter.
A side affect is that on a room upgrade the spam checker callback is
called *after* doing some work to calculate the state rather than
before. However, I hope that this is acceptable given the relative
infrequency of room upgrades.
This change adds a new configuration
`user_directory.exclude_remote_users`, which defaults to False.
When set to True, remote users will not appear in user directory search
results.

This should be reviewed commit by commit.
It adds a few admin servlets that are used by MAS when in delegation
mode to workers
