Pull request overview

This PR updates the Behave-based integration test harness to fix “verify package” test failures, primarily by making system CA bundle overriding configurable (so tests that need outbound TLS can keep the distro CA store) and by adjusting how MiNiFi is launched when running from an RPM/FHS-style installation.

Changes:

• Introduce override_default_ca_cert_files on the Behave test context, defaulting to True in the shared hooks.
• Disable CA-bundle overriding for the Python extension feature tests so outbound HTTPS (e.g., package/download traffic) can use the image’s default CA store.
• Update the Python examples startup command to invoke the minifi executable directly (instead of minifi.sh run), aligning with RPM/FHS layouts.
