ui: datastore selector: move maintenance mode inline with icon

else it's a lot of wasted space for the ordinary case, that hasn't
permanent maintenance modes activated, and even if, their admins
should be used to it, so not the best space/usability ROI there
either.

Just use the icon as visual clue and add a tooltip for the
maintenance mode info.
