Rename iolimit to blockio.

Browse Source 
After discussion with DB we decided to rename the new iolimit
element as it creates the impression it would be there to
limit (i.e. throttle) I/O instead of specifying immutable
characteristics of a block device.
This is also backed by the fact that the term I/O Limits has
vanished from newer storage admin documentation.
