The ipautil.run function now returns an object with returncode and
output are accessible as attributes.
The stdout and stderr of all commands are logged (unless skip_output is given).
The stdout/stderr contents must be explicitly requested with a keyword
argument, otherwise they are None.
This is because in Python 3, the output needs to be decoded, and that can
fail if it's not decodable (human-readable) text.
The raw (bytes) output is always available from the result object,
as is "leniently" decoded output suitable for logging.
All calls are changed to reflect this.
A use of Popen in cainstance is changed to ipautil.run.

In Python 3, `print` is no longer a statement. Call it as a function
everywhere, and include the future import to remove the statement
in Python 2 code as well.
