Hadi Moshayedi e10f415de5 Rhizome: Support Ubiblk v0.2.0.
Ubiblk v0.2.0 made several performance improvements:

- Reduced number of syscalls per IO,
- Improved flush performance by avoiding unnecessary metadata flushes,
- Added cpu pinning,
- Added write-through mode.

We'll keep v0.1-7 as supported and the default version while v0.2.0 is
being tested.
