Fix CI: pylint too-many-public-methods and DuplicateFilter test bleed

- Add pylint disable for too-many-public-methods on TestOTLPSpanExporter
  (21 methods exceeds limit of 20, matching existing log exporter fix)
- Reset DuplicateFilter state between log exporter tests via setUp() to
  prevent log suppression from 413 tests bleeding into
  test_export_no_collector_available
