bolt task should handle when ipa command returns 2
For instance when operator ask to delete a user that does not exist.
In this situation the task should display the ipa message and return 0 to be understand by bolt as not failed.
If the task is to ensure that user
foo is not present, then it looks already done when the user
foo does not exist yet.
EXIT STATUS 0 if the command was successful 1 if an error occurred 2 if an entry is not found
