Change Details

Implemented as part of [ENG-10603](https://linear.app/comm/issue/ENG-10603/biggest-risk-factor-out-code-from-databasequeryexecutor) The goal is to make `connectionManager` non-static. We first need to convert the methods that use it. `thread_local SQLiteQueryExecutor instance;` in DatabaseManager works, but it is not clean, but this is going to change in TBD. Depends on D14731
