## Problem description
During tests we found concurrency issues in the relational table
projections. Tests got flaky if a table (e.g. organization domains) had
too many foreign keys to tables which were projected by another handler.
## Resolution
The projections of the relational tables got merged into one handler to
enforce sequential reduction of events.

# Which Problems Are Solved
After a user is deactivated, their sessions are still valid. When the
user is redirected to login page, they're stuck in a loop on a blank
page on the `users/me` endpoint as the user's session is still valid.
# How the Problems Are Solved
By terminating a deactivated user's session. This is done by:
- Adding a new reducer in session projection to delete sessions for
`UserDeactivatedEvent`, `UserLockedEvent` and `UserRemovedEvent` events
- Adding a new reducer in the relation session projection to delete
sessions based on `UserDeactivatedEvent`, `UserLockedEvent` events
# Additional Changes
N/A
# Additional Context
- Closes https://github.com/zitadel/zitadel/issues/10307
- todo: add integration test cases for relational session reducers based
on user deactivated, locked, deleted events
# Which Problems Are Solved
As part of going to a relation storage model, we need to implement the
repository for handling sessions and their events.
# How the Problems Are Solved
- Adds a migration step to create the necessary tables and types in the
database.
- Adds the repository implementation for sessions.
- Implements a projection handler for session events to handle the
events written by the old command handlers.
- Updates the `Session` type and `SessionRepository` interface:
- added `CreatorID`
- Adjusted `Delete` method to return amount of affected columns
- Removed sub-repository clumns from the main interface
- Added `CreatorIDCondition`, `ExpirationCondition`, `ExistsFactor` and
`ExistsMetadata`
- Removed `SetUserAgent`
- Methods of `SessionFactor` and `SessionChallenge` have been made
public
- fixed enumer on `SessionFactorType`
- Adds a `JSON` type to the repository package to easy can JSON columns,
resp. jsonb object inside a property of a `JSONArray` object.
- Adds a `NoChange` interface, which can be implemented to signal that a
`Change` interface implementation is not writing any changes to the
statement builder, e.g. `CTEChange`
# Additional Changes
- Fixes the operators enums. `TextOperations` had wrong comments and
`NumberOperations` additionally also had from comparisons.
- Fixes downgrade of migration step 008.
