Some of the extensions in IPA currently do not return any values
from their respective command methods. This results in a lack of a
paper trail of the command_result value to the point where it is
not possible to know more information than a boolean result of if
a command succeeded or failed.
This change adds more logging to the extensions and provides return
values which are used in the command_result property on
(Async|Sync)CommandResult instances to provide useful debug info.
While creating this patch several unit tests for *CommandResult objects
were found to be using invalid data that would not pass validation
if returned in API results. Those have been corrected in this patch.
