Enhanced KVM Storage QoS

Registered by Simon Dodsley

QEMU 1.7 adds additional iotune parameters to enhance the block storage quality of service provided.

This blueprint allows for these additions.

The added values are related to burst values and setting max (burst) values for read, write and total IOPs and bandwidth. Also added is the setting of block size for IOs.
