High: external/ec2: Avoid unicode errors and improve performance (bsc#1088656)
    
    Originally by stsch@amazon.de:
    
    All AWS CLI describe commands have been changed to report the result directly.
    
    This has the following advantages:
    
    * No more unicode errors when other tags use UNICODE characters.
    * No more interpreatation errors with aws and grep if the text format changes.
    * Faster execution due to significantly reduced result sets.
