Description

Add two new variables, associate_public_ip_address and target_ami_name_prefix.

Motivation

The Packer EBS Builder includes a variable to force the association of a public IP address to the builder. This is needed when using a non-default VPC that does not automatically assign public IP addresses. Exposing that variable to users would be beneficial.

The ami_name_prefix variable is currently misleading. The description is "The prefix to use when creating the AMI name", which is accurate, but this same prefix is used to locate the source AMI when building. This means the variable cannot be changed to customize the target AMI name. We can expose a second variable that is specifically used for the target AMI name and update the ami_name_prefix variable to more accurately describe its use.
