In the production version (v1-oreo) there is no check for internet availability, and no mechanism to handle failure. Which result in blocked eDrive if initialization failed.

This MR provide a new mechanism for initialization that handle failure and no network. If there some failure, the task are retried later as soon as all condition are met.
