Armando Neto 3ccd512dab Disable Pylint 2.0 violations 
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.
  https://docs.python.org/3/library/subprocess.html#popen-constructor

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

Auto Membership Rule.
""") + _("""
Bring clarity to the membership of hosts and users by configuring inclusive
or exclusive regex patterns, you can automatically assign a new entries into
a group or hostgroup based upon attribute information.
""") + _("""
A rule is directly associated with a group by name, so you cannot create
a rule without an accompanying group or hostgroup.
""") + _("""
A condition is a regular expression used by 389-ds to match a new incoming
entry with an automember rule. If it matches an inclusive rule then the
entry is added to the appropriate group or hostgroup.
""") + _("""
A default group or hostgroup could be specified for entries that do not
match any rule. In case of user entries this group will be a fallback group
because all users are by default members of group specified in IPA config.
""") + _("""
The automember-rebuild command can be used to retroactively run automember rules
against existing entries, thus rebuilding their membership.
""") + _("""
EXAMPLES:
""") + _("""
Add the initial group or hostgroup:
ipa hostgroup-add --desc="Web Servers" webservers
ipa group-add --desc="Developers" devel
