Code Issues Proposed changes

Task base deployment

Browse Source 
* async task: puppet, shell, cobbler, sync, noop and reboot;
* not async: upload file, upload files, copy files;
* new report format based on task progress instead of log;
* support union graph deployment: pre/post tasks included in main graph;
* plugins tasks also included in main graph;
* support previous failt tollerance strategy (percent of failed nodes).
* add tests.

Implements: blueprint task-based-deployment-astute
