Summary:
Introduce a handler that:

1. Reads the token from core module
2. Listens for its changes
3. Updates the store with the most recent value

Depends on D10866

Test Plan: Call commCoreModule.setCommServicesAuthMetadata and check if the token in Redux is updated. Add a timeout with a call to commCoreModule.setCommServicesAuthMetadata and check if it results in the token being updated.
