// Describes the progress of the AMI store tasks. You can describe the store tasks
// for specified AMIs. If you don't specify the AMIs, you get a paginated list of
// store tasks from the last 31 days. For each AMI task, the response indicates if
// the task is InProgress, Completed, or Failed. For tasks InProgress, the response
// shows the estimated progress as a percentage. Tasks are listed in reverse
// chronological order. Currently, only tasks from the past 31 days can be viewed.
// To use this API, you must have the required permissions. For more information,
// see Permissions for storing and restoring AMIs using Amazon S3
