Fix the following violations aiming to support Pylint 2.0
- `unneeded-not` (C0113):
Consider changing "not item in items" to "item not in items" used
when a boolean expression contains an unneeded negation.
- `useless-import-alias` (C0414):
Import alias does not rename original package Used when an import
alias is same as original package.e.g using import numpy as numpy
instead of import numpy as np
- `raising-format-tuple` (W0715):
Exception arguments suggest string formatting might be intended Used
when passing multiple arguments to an exception constructor, the
first of them a string literal containing what appears to be
placeholders intended for formatting
- `bad-continuation` (C0330):
This was already included on the disable list, although with current
version of pylint (2.0.0.dev2) violations at the end of the files
are not being ignored.
See: https://github.com/PyCQA/pylint/issues/2278
- `try-except-raise` (E0705):
The except handler raises immediately Used when an except handler
uses raise as its first or only operator. This is useless because it
raises back the exception immediately. Remove the raise operator or
the entire try-except-raise block!
- `consider-using-set-comprehension` (R1718):
Consider using a set comprehension Although there is nothing
syntactically wrong with this code, it is hard to read and can be
simplified to a set comprehension.Also it is faster since you don't
need to create another transient list
- `dict-keys-not-iterating` (W1655):
dict.keys referenced when not iterating Used when dict.keys is
referenced in a non-iterating context (returns an iterator in
Python 3)
- `comprehension-escape` (W1662):
Using a variable that was bound inside a comprehension Emitted when
using a variable, that was bound in a comprehension handler, outside
of the comprehension itself. On Python 3 these variables will be
deleted outside of the comprehension.

Aiming to support pylint 2.0 some functions and methods must have their
return statements updated in order to fix two new violations:
- `useless-return` (R1711):
Useless return at end of function or method Emitted when a single
"return" or "return None" statement is found at the end of function
or method definition. This statement can safely be removed because
Python will implicitly return None
- `inconsistent-return-statements` (R1710):
Either all return statements in a function should return an
expression, or none of them should. According to PEP8, if any return
statement returns an expression, any return statements where no value
is returned should explicitly state this as return None, and an
explicit return statement should be present at the end of the
function (if reachable)

Python 3 has moved all collection abstract base classes to
collections.abc. Python 3.7 started to deprecate the old aliases.
The whole import block needs to be protected with import-error and
no-name-in-module, because Python 2 doesn't have collections.abc module and
collections.abc.Mapping, while Python 3 doesn't have collections.Mapping.

Instead of symlinks and build-time configuration the ipaplatform module
is now able to auto-detect platforms on import time. The meta importer
uses the platform 'ID' from /etc/os-releases. It falls back to 'ID_LIKE'
on platforms like CentOS, which has ID=centos and ID_LIKE="rhel fedora".
The meta importer is able to handle namespace packages and the
ipaplatform package has been turned into a namespace package in order to
support external platform specifications.

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.

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.
