Resize of rbd image
We want to be able to resize the rbd image. Snapshots should be maintained and should have a size associated with them.

There is a refresh /sys/class/.. interface, however, resizing of an image should be lock protected, and probably shouldn't happen when an image is mounted on the client. There are certain issues that can happen when resizing a block device after being mapped (or even worse -- with in-flight i/o) and these should be avoided.

resizing hte underlying block device has been possible with ext3 since RHEL 4 (~5 years?), so this is something we should support.
