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, the base64.b64decode function raises binascii.Error (a ValueError
subclass) when it finds incorrect padding. In Python 2 it raises TypeError.
Callers should usually handle ValueError; unless they are specifically
concerned with handling base64 padding issues).
In some cases, callers should handle ValueError:
- ipalib.pkcs10 (get_friendlyname, load_certificate_request): callers should
handle ValueError
- ipalib.x509 (load_certificate*, get_*): callers should handle ValueError
In other cases ValueError is handled:
- ipalib.parameters
- ipapython.ssh
- ipalib.rpc (json_decode_binary - callers already expect ValueError)
- ipaserver.install.ldapupdate
Elsewhere no error handling is done, because values come from trusted
sources, or are pre-validated:
- vault plugin
- ipaserver.install.cainstance
- ipaserver.install.certs
- ipaserver.install.ipa_otptoken_import

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.

Python 2 has keys()/values()/items(), which return lists,
iterkeys()/itervalues()/iteritems(), which return iterators,
and viewkeys()/viewvalues()/viewitems() which return views.
Python 3 has only keys()/values()/items(), which return views.
To get iterators, one can use iter() or a for loop/comprehension;
for lists there's the list() constructor.
When iterating through the entire dict, without modifying the dict,
the difference between Python 2's items() and iteritems() is
negligible, especially on small dicts (the main overhead is
extra memory, not CPU time). In the interest of simpler code,
this patch changes many instances of iteritems() to items(),
iterkeys() to keys() etc.
In other cases, helpers like six.itervalues are used.
