[PATCH v6 02/16] python: Reduce strictness of pylint's duplicate-code check

[Emanuele Giuseppe Esposito <eesposit@redhat.com>]

From: John Snow <jsnow@redhat.com>

Pylint prior to 2.8.3 (We pin at >= 2.8.0) includes function and method
signatures as part of its duplicate checking algorithm. This check does
not listen to pragmas, so the only way to disable it is to turn it off
completely or increase the minimum duplicate lines so that it doesn't
trigger for functions with long, multi-line signatures.

When we decide to upgrade to pylint 2.8.3 or greater, we will be able to
use 'ignore-signatures = true' to the config instead.

I'd prefer not to keep us on the very bleeding edge of pylint if I can
help it -- 2.8.3 came out only three days ago at time of writing.
