PHASE 1 NOTICES
- we need a clear and simple insturctions how to setup bucket on google cloud and get credentials like service account json.
- google/cloud-storage SDK missing. Run composer install in plugin directory. -> this needs to be autorun on plugin activation


PHASE 2 NOTICES
- all migration files failed
- we need log of offloading files to be stored in the plugin, and that is where it reads it
- failed media items must be addressed in logs, what media items failed to have clear view of what media items failed
- on reload the process must not be restarted or failed, but continue where it was
- i see ajax is pinging, that is good. but that must face changes to the frontend imiditaelly (counter for run migration cards (processing, offloaded, failed, etc..)) 
- currently just keeps items PENDING
