* Add `PerformInvite`
* More tweaks
* Fix metric name
* Fix LookupStateIDs
* Lots of changes to clients
* Some serverside stuff
* Some error handling
* Use paths as metric names
* Revert "Use paths as metric names"
This reverts commit a9323a6a34.
* Namespace metric names
* Remove duplicate entry
* Remove another duplicate entry
* Tweak error handling
* Some more tweaks
* Update error behaviour
* Some more error tweaking
* Fix API path for `PerformDeleteKeys`
* Fix another path
* Tweak federation client proxying
* Fix another path
* Don't return typed nils
* Some more tweaks, not that it makes any difference
* Tweak federation client proxying
* Maybe fix the key backup test

// FE GME TXN

// A ---> B ---> C ---> D

// TXN=event in the txn, GME=response to /get_missing_events, FE=roomserver's forward extremity. Should result in:

// - /state_ids?event=B is requested, then /event/B to get the state AFTER B. B is a state event.
