A new IBrokerageCashSynchronizer interface has been added to allow brokerage implementations to handle the cash sync process. Most of the cash sync logic has been moved from the BrokerageTransactionHandler to the base Brokerage class.
The IB brokerage will not attempt to perform cash sync during server reset times, respecting the different regional schedules (see also #3413).
- For backtesting the algorithm thread will sequentially process pending
order requests
- Adding new non blocking `BusyCollection`
- Updating `UpdateOrderRegressionAlgorithm` that suffered of a race
condition: it supposed `OnOrderEvent` would be called after the call to
`Transactions.AddOrder()` was finished
- `GetCashBalance()` will return a `List<CashAmount>`, will not need to
set conversion rates, which requires knowing what the account currency is.
- Removing `Global.Holding` conversion rate field. It wasn't being used
and required knowing what the account currency is.
- Adding equality operators for `CashAmount`. Adding unit tests.
