onShutdown

Called when this Module has been determined to be shutdown. This could happen for the following reasons:

• Updated settings have been received with enabled set to false

• The Module itself has returned null from its updateConfiguration method, thereby implying that the Module cannot operate with the latest configuration.

• The Tealium instance that this Module is running in, has been shutdown.

Modules should handle any required cleanup; disposing of any internal subscriptions or unsubscribing from any services etc.
