Martin Regen 9138bb90e0 Support for subclassing of client sessions, subscriptions and monitored items (#2384) ...

Currently, due to some internal cloning of sessions, subscriptions and monitored items it is not possible to use subclassed variants which are properly recreated after a session reconnect.

- Add a  `ISessionInstantiator` interface to allow to subclass a `Session` and override virtual function.
- Add a `Subscription.CloneSubscription` and `MonitoredItem.CloneMonitoredItem` virtual method to recreate those with event handlers and client handles.
- A sample implementation with `TestableXXX` classes is provided to test the BadInvalidTimestamp fix by injecting modified timestamps in the session class.
- Remove duplicate `IDisposable` with `Session`. `IClientBase` is disposable already.
- adds `knownTypes` parameter to `Session.Load` and `Session.Save` to support save and restore of custom Subscriptions and Monitored items.

bug fixes:
- IOP: an empty DataTypeDictionary throws an exception when loaded by the complex type system, server are allowed to leave it empty to save memory.
- BadInvalidTimestamp should not be returned when the timestamp in the requestheader is out of sync. #2364
