Based on analysis that includes old versions down to 4.0 (latest unsupported version), the syncFromConfig argument of the _flushRoutingTableCacheUpdates command is never set to false. Consequently, all the related logic when set to false can be eliminated.

Goal of this task is to evaluate that statement and possibly get rig of the related logic.

Based on an analysis that includes older versions up to 4.0 (latest version not supported), the syncFromConfig argument of the _flushRoutingTableCacheUpdates command is never set to false. As a result, all related logic when set to false can be removed.

The goal of this task is to evaluate that statement, possibly remove the argument and change the related logic assuming it is always true.

Open questions:
1. Is this command used only internally between the cluster processes?
2. Is this used by our support team?
3. In that case, do they pass the syncFromConfig argument and why?
