fix: re-enabling several globally disabled lint rules (apache#10957)

* Removed global pylintrc rule: bad-continuation. Black repaired it.

* Enable global pylintrc rule: duplicate-code. It might help with providing clean code and future refactors.

* Removed global rule `dict-iter-method` since Python3 doesn't support methods: dict.iterkeys(), itervalues() or iteritems()

* Removing global disabler rule `invalid-unary-operand-type`, because all unary operators are used on objects which supports those operations
