Purge soft-deleted Watcher objects

Registered by David TARDIVEL on 2016-02-03

Watcher never deletes data from its DBs and uses only soft deleting (There is special column in each table that indicates that entry is deleted). We keep these data from potential future ML processing in order to improve Watcher auditing recommendations. However, we shall provide a purge mechanism to Cloud Admin in order to limit the size of this database and make sure it does not increase too much.
