This commit add new VDI steps named step_{attach,detach,find,upload}_vdi
- attach/detach are self-explanatory; can specify CD or Floppy
- find finds a VDI by name-label and stores the uuid
- upload uploads a VDI from a local disk image and stores the uuid
In order to demonstrate the new VDI code, this commit trivially adds:
- support for uploading ISOs again (dependent on unmerged XAPI patch)
- initial floppy upload/attach support (dependent on currently-broken
XAPI patch)
- initial XenServer Tools support
