v0.3.4

Bugs

• Fixed result caching bug for AwsQuantumTask if state() or metadata() is called after a task has timed out and the task is in a completed state

Feature

• Reduced the required arguments of AwsQuantumTask to the task ARN
  ** Note: this is a breaking change if a user manually instantiates AwsQuantumTask() because it no longer accepts the argument results_formatter.
  ** New way of instantiating: task = AwsQuantumTask(arn='your_task_arn')
