Handles creating, partitioning, and formatting a new EBS volume. By
default this class will format the entire drive (without partitioning)
using the ext3 filesystem.
host_instance - EC2 instance to use when formatting volume. must exist
in the same zone as the new volume. if not specified this class will look
for host instances in the @sc-volumecreator security group. If it can't
find an instance in the @sc-volumecreator group that matches the zone of
the new volume, a new instance is launched.
shutdown_instance - True will shutdown the host instance after volume
creation
