Make data source redundancy config more flexible

Some SCADA vendors are still only natively implementing OPC Classic so if one wants to use OPC UA, then a wrapper is needed. If that SCADA is configured in a redundant pair, it is not always true that the wrapper is aware of that or not aware of his corresponding wrapper running on the redundant server. In such a case the Redundancy Support tag is 0-None and the Service Level tag (if present) has unknown behaviour. Right now the only way to manage that is by configuring two data sources and archive all tags twice (once each data source) and find a way to hide this complexity from the end-user (not to mention storage and licensing inefficiencies). It would be nice if the Connector could be made to monitor an alternate tag to determine data source health and switch to a second data source if needed. Probably some sort of heart beat tag would be used in a purely cold standby way (since it is not native to OPC UA we may want to wait a period of time to ensure that our heart is not beating).
