New Pylint (2.4.3) catches several new 'true problems'. At the same
time, it warns about things that are massively and reasonably
employed in FreeIPA.

Globally disabling the following violations:
- `assignment-from-no-return` (E1111):
Assigning to function call which doesn't return. Used when an
assignment is done on a function call but the inferred function
doesn't return anything.
- `keyword-arg-before-vararg` (W1113):
Keyword argument before variable positional arguments list in the
definition of %s function When defining a keyword argument before
variable positional arguments, one can end up in having multiple
values passed for the aforementioned parameter in case the method is
called with keyword arguments.
Locally disabling the following:
- `subprocess-popen-preexec-fn` (W1509):
Using preexec_fn keyword which may be unsafe in the presence of
threads The preexec_fn parameter is not safe to use in the presence
of threads in your application. The child process could deadlock
before exec is called. If you must use it, keep it trivial! Minimize
the number of libraries you call into.

Fixed violations:
- `bad-mcs-classmethod-argument` (C0204):
Metaclass class method %s should have %s as first argument Used when
a metaclass class method has a first argument named differently than
the value specified in valid-metaclass-classmethod-first-arg option
(default to "mcs"), recommended to easily differentiate them from
regular instance methods.
- Note: Actually `cls` is the default first arg for `__new__`.
- `consider-using-get` (R1715):
Consider using dict.get for getting values from a dict if a key is
present or a default if not Using the builtin dict.get for getting a
value from a dictionary if a key is present or a default if not, is
simpler and considered more idiomatic, although sometimes a bit slower

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)

The server installation and uninstallation overlaps both the
server and client installers. The output could be confusing
with a server uninstall finishing with the message:
The ipa-client-install command was successful
This was in part due to the fact that the server was not
configured with a console format and verbose was False which
meant that no logger messages were displayed at all.
In order to suppress client installation errors and avoid
confusion add a list of errors to ignore. If a server install
was not successful and hadn't gotten far enough to do the
client install then we shouldn't complain loudly about it.

The AdminTool class purports to "call sys.exit() with the return
value" but most of the run implementations returned no value, or
the methods they called returned nothing so there was nothing to
return, so this was a no-op.
The fix is to capture and bubble up the return values which will
return 1 if any exceptions are caught.
This potentially affects other users in that when executing the
steps of an installer or uninstaller the highest return code
will be the exit value of that installer.
Don't use the Continuous class because it doesn't add any
value and makes catching the exceptions more difficult.

Add the 'constructor' type to IPAOption to allow parsing arbitrary

When using this type, supply the 'constructor' attribute with the

The 'knob' interface remains unchanged but now accepts arbitrary
