#
# ==== Parameters
# * availability_zone<~String> - availability zone to create volume in
# * size<~Integer> - Size in GiBs for volume. Must be between 1 and 1024.
# * options<~Hash>
# * 'SnapshotId'<~String> - Optional, snapshot to create volume from
# * 'VolumeType'<~String> - Optional, volume type. standard or io1, default is standard.
