# Attach an Amazon EBS volume with a running instance, exposing as specified device
#
# ==== Parameters
# * instance_id<~String> - Id of instance to associate volume with
# * volume_id<~String> - Id of amazon EBS volume to associate with instance
# * device<~String> - Specifies how the device is exposed to the instance (e.g. "/dev/sdh")
#
# ==== Returns
# * response<~Excon::Response>:
# * body<~Hash>:
# * 'attachTime'<~Time> - Time of attachment was initiated at
# * 'device'<~String> - Device as it is exposed to the instance
# * 'instanceId'<~String> - Id of instance for volume
# * 'requestId'<~String> - Id of request
# * 'status'<~String> - Status of volume
# * 'volumeId'<~String> - Reference to volume
