RocketMQSourceFunction doesn't have the ability to dynamically sense topic routing changes.

RocketMQSourceFunction doesn't have the ability to dynamically sense topic routing changes, if topic route info changes, it would throw RuntimeException without resolving that:

Start at RocketMQSourceFunction and reproduce the failure when topic route information changes. Trace the routing and exception path shown in the issue; done means the source dynamically detects route changes without throwing an unresolved RuntimeException.
