Change default metadata from 0.90 to 1.1 

1.1 is more flexible in a number of ways and is safer.
0.90 is still fully supported.
1.0 should possibly be used for RAID1 arrays that you
want to boot off, depending on your boot loader.

Use the original 0.90 format superblock. This format limits arrays to
28 component devices and limits component devices of levels 1 and
greater to 2 terabytes.

Use the new version-1 format superblock. This has few restrictions.
