# Launch specified instances
#
# ==== Parameters
# * image_id<~String> - Id of machine image to load on instances
# * min_count<~Integer> - Minimum number of instances to launch. If this
# exceeds the count of available instances, no instances will be
# launched. Must be between 1 and maximum allowed for your account
# (by default the maximum for an account is 20)
# * max_count<~Integer> - Maximum number of instances to launch. If this
# exceeds the number of available instances, the largest possible
# number of instances above min_count will be launched instead. Must
# be between 1 and maximum allowed for you account
# (by default the maximum for an account is 20)
# * options<~Hash>:
# * 'Placement.AvailabilityZone'<~String> - Placement constraint for instances
# * 'Placement.GroupName'<~String> - Name of existing placement group to launch instance into
# * 'Placement.Tenancy'<~String> - Tenancy option in ['dedicated', 'default'], defaults to 'default'
# * 'BlockDeviceMapping'<~Array>: array of hashes
# * 'DeviceName'<~String> - where the volume will be exposed to instance
# * 'VirtualName'<~String> - volume virtual device name
# * 'Ebs.SnapshotId'<~String> - id of snapshot to boot volume from
# * 'Ebs.VolumeSize'<~String> - size of volume in GiBs required unless snapshot is specified

# * 'ClientToken'<~String> - unique case-sensitive token for ensuring idempotency
# * 'DisableApiTermination'<~Boolean> - specifies whether or not to allow termination of the instance from the api
# * 'SecurityGroup'<~Array> or <~String> - Name of security group(s) for instances (not supported for VPC)
# * 'SecurityGroupId'<~Array> or <~String> - id's of security group(s) for instances, use this or SecurityGroup
# * 'InstanceInitiatedShutdownBehaviour'<~String> - specifies whether volumes are stopped or terminated when instance is shutdown, in [stop, terminate]
# * 'InstanceType'<~String> - Type of instance to boot. Valid options
# in ['t1.micro', 'm1.small', 'm1.large', 'm1.xlarge', 'c1.medium', 'c1.xlarge', 'm2.xlarge', m2.2xlarge', 'm2.4xlarge', 'cc1.4xlarge', 'cc2.8xlarge', 'cg1.4xlarge']
# default is 'm1.small'
# * 'KernelId'<~String> - Id of kernel with which to launch
# * 'KeyName'<~String> - Name of a keypair to add to booting instances
# * 'Monitoring.Enabled'<~Boolean> - Enables monitoring, defaults to
# disabled
# * 'PrivateIpAddress<~String> - VPC option to specify ip address within subnet
# * 'RamdiskId'<~String> - Id of ramdisk with which to launch
# * 'SubnetId'<~String> - VPC option to specify subnet to launch instance into
# * 'UserData'<~String> - Additional data to provide to booting instances
# * 'EbsOptimized'<~Boolean> - Whether the instance is optimized for EBS I/O

# * 'attachTime'<~Time> - time of volume attachment
# * 'deleteOnTermination'<~Boolean> - whether or not to delete volume on termination
# * 'deviceName'<~String> - specifies how volume is exposed to instance
# * 'status'<~String> - status of attached volume
# * 'volumeId'<~String> - Id of attached volume
# * 'dnsName'<~String> - public dns name, blank until instance is running
