Title:
  Can not set volume attributes at instance launch by EC2 API

Status in EC2 API:
  New
Status in OpenStack Compute (Nova):
  Confirmed

Bug description:
  AWS allows to change block device attributes (such as volume size,
  delete on termination behavior, existence) at instance launch.

  For example, image xxx has devices:
  vda, size 10, delete on termination
  vdb, size 100, delete on termination
  vdc, size 100, delete on termination
  We can run an instance by
  euca-run-instances ... xxx -b /dev/vda=:20 -b /dev/vdb=::false -b /dev/vdc=none
  to get the instance with devices:
  vda, size 20, delete on termination
  vdb, size 100, not delete on termination

  For Nova we get now:
  $ euca-run-instances --instance-type m1.nano -b /dev/vda=::true ami-0000000a
  euca-run-instances: error (InvalidBDMFormat): Block Device Mapping is Invalid: Unrecognized legacy format.
