What is the current behavior? (You can also link to an open issue here)
Moving basic auth in ADF Alfresco/alfresco-ng2-components#8689, the content authentication will be handled by the content-auth.ts and the e2e that open a file with the file-viewer failed because the alf_ticket is not added to the contentApi. Since the content-auth.ts can't update AlfrescoApiConfig, it's needed to get the ticketEcm from the Storage.

What is the new behavior?
The Storage is handled as Singleton, the instance is created by AlfrescoApi and the AlfrescoApiClient can access the Storage the ticketEcm https://github.com/Alfresco/alfresco-js-api/blob/dev-alepore-AAE-12502/src/alfrescoApiClient.ts#L246
