Added more meta-info loaded dynamically
fixed: Audit brigde says 'finish' when an audits ends, but web API is docummented as 'finished'. We need to transform the word
added test that simulates all audit process: creation, waiting, get status, partial progress, and get all type of results
Fixed get state method. Now is stable and update the status well. Only get_status can change audit state, removed any other places that change their state. Changed statid dict with extensions by format, for a dinamic dict, loaded from .yaml file
added new formats and new dynamic vars
