lvdisplay: enhance LV status output for raid(0) In case legs of a raid0 LV are removed, the lvdisplay command still reports 'available' though raid0 is not providing any resilience compared to the other raid levels. Also lvdisplay does not display '(partial)' in case of missing raid0 legs as oposed to the lvs command. Enhance lvdisplay to report "NOT available" for any RaidLV type in case too many legs are inaccessible hence causing data loss. I.e. any leg for raid0, all for raid1, more than 1 for raid4/5, more than 2 for raid6 and in case of completely lost mirror groups for raid10. Add test/shell/lvdisplay-raid.sh. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1872678
