Handle remote driver not loaded situation
Handle remote driver not loaded situation

An error in our code could lead to remote being used by sahara-api.
Since remote is not available there, an exception will be thrown like
the one in bug #1325989. We should give user a hint that switching to
sahara-all might fix the issue.
