Add a class UnpersistedEventContext to allow for the batching up of storing state groups (#14675)
* add class UnpersistedEventContext * modify create new client event to create unpersistedeventcontexts * persist event contexts after creation * fix tests to persist unpersisted event contexts * cleanup * misc lints + cleanup * changelog + fix comments * lints * fix batch insertion? * reduce redundant calculation * add unpersisted event classes * rework compute_event_context, split into function that returns unpersisted event context and then persists it * use calculate_context_info to create unpersisted event contexts * update typing * $%#^&* * black * fix comments and consolidate classes, use attr.s for class * requested changes * lint * requested changes * requested changes * refactor to be stupidly explicit * clearer renaming and flow * make partial state non-optional * update docstrings --------- Co-authored-by: Erik Johnston <erik@matrix.org>

The event context holds information about the state groups for an event. It is important
|
||||
to remember that an event technically has two state groups: the state group before the
|
||||
event, and the state group after the event. If the event is not a state event, the state
|
||||
group will not change (ie the state group before the event will be the same as the state
|
||||
group after the event), but if it is a state event the state group before the event
|
||||
will differ from the state group after the event.
|
||||
This is a version of an EventContext before the new state group (if any) has been
|
||||
computed and stored. It contains information about the state before the event (which
|
||||
also may be the information after the event, if the event is not a state event). The
|

UnpersistedEventContext must be converted into an EventContext by calling the method
|
||||
'persist' on it before it is suitable to be sent to the DB for processing.

|
||||
The state group after the event. This will always be None until it is persisted.

|
||||
state_group_before_event.
