Re-introduce the outbound federation proxy (#15913)

Allow configuring the set of workers to proxy outbound federation traffic through (`outbound_federation_restricted_to`).

This is useful when you have a worker setup with `federation_sender` instances responsible for sending outbound federation requests and want to make sure *all* outbound federation traffic goes through those instances. Before this change, the generic workers would still contact federation themselves for things like profile lookups, backfill, etc. This PR allows you to set more strict access controls/firewall for all workers and only allow the `federation_sender`'s to contact the outside world.

#### Restrict outbound federation traffic to a specific set of workers
The
[`outbound_federation_restricted_to`](usage/configuration/config_documentation.md#outbound_federation_restricted_to)
configuration is useful to make sure outbound federation traffic only goes through a
specified subset of workers. This allows you to set more strict access controls (like a
firewall) for all workers and only allow the `federation_sender`'s to contact the
outside world.
```yaml
instance_map:
main:
host: localhost
port: 8030
federation_sender1:
host: localhost
port: 8034
outbound_federation_restricted_to:
- federation_sender1
worker_replication_secret: "secret_secret"
```
#### Background tasks
There is also support for moving background tasks to a separate
