Revert "[BUGFIX] Do not turn storages automatically offline"

This reverts commit 157e1f26.

This change introduced bugs with storages that were explicitly marked offline. 
Besides that, it removed pubic API without deprecation
and lacked (clearly documented) concept on the behavior in the error case.
