This extends the dendrite monolith for pinecone to integrate the s&f
features into the mobile apps.
Also makes a few tweaks to federation queueing/statistics to make some
edge cases more robust.
This adds store & forward relays into dendrite for p2p.
A few things have changed:
- new relay api serves new http endpoints for s&f federation
- updated outbound federation queueing which will attempt to forward
using s&f if appropriate
- database entries to track s&f relays for other nodes
Beforehand we disabled HTTP keepalives to prevent ambient system
resources from being used by excess idle connections. Now that we've
fixed some bugs in the federation API and device list updater, this
situation is now much better and we don't open so many remote
connections anyway.
Keepalives allow us to not have to handshake TLS so often (which is
quite expensive) and reusing an idle connection is much faster than
having to open a new one. This can help with response times when talking
to remote federated servers.
This PR also adds a new option to disable keepalives if needed:
```
# Disable HTTP keepalives, which also prevents connection reuse. Dendrite will typically
# keep HTTP connections open to remote hosts for 5 minutes as they can be reused much
# more quickly than opening new connections each time. Disabling keepalives will close
# HTTP connections immediately after a successful request but may result in more CPU and
# memory being used on TLS handshakes for each new connection instead.
disable_http_keepalives: false
```
This makes the following changes:
* The various `Defaults` functions are now responsible for setting sane defaults if `generate` is specified, rather than hiding them in `generate-config`
* Some configuration options have been marked as `omitempty` so that they don't appear in generated configs unnecessarily (monolith-specific vs. polylith-specific options)
* A new option `-polylith` has been added to `generate-config` to create a config that makes sense for polylith deployments (i.e. including the internal/external API listeners and per-component database sections)
* A new option `-normalise` has been added to `generate-config` to take an existing file and add any missing options and/or defaults
* Remove all federation_certificates occurencs
This configuration value has not been used since 2019 apparently, and indeed
it is never really used in the code base. So remove all traces of it from
the various configuration files.
Also remove the unused variable FederationCertificatePaths

* setup/config/config_test.go: remove federation_sender config snippet
The federation_sender: section was folded into the federation_api some
time ago, and this seems to be the only leftover in the code base.
So remove it.
* Initial federation sender -> federation API refactoring
* Move base into own package, avoids import cycle
* Fix build errors
* Fix tests
* Add signing key server tables
* Try to fold signing key server into federation API
* Fix dendritejs builds
* Update embedded interfaces
* Fix panic, fix lint error
* Update configs, docker
* Rename some things
* Reuse same keyring on the implementing side
* Fix federation tests, `NewBaseDendrite` can accept freeform options
* Fix build
* Update create_db, configs
* Name tables back
* Don't rename federationsender consumer for now
