* modify utils.check_version to accept a default version to check against, and remove nested error when version check fails as it is overzealous Update test file paths in test_utils in case someone runs tests as root which actually can write to fake devices and therefore break the tests * Updated clients for 1.16 Added pylint exclusions for known but unimportant complaints Added workaround for NiFi 9470 by providing default inherited_parameter_contexts per advice from Chris Sampson in NiPyAPI Issue #305 Fixes #305 Updated NiFi and Registry versions in Docker compose configs to use latest 1.16.1 builds Signed-off-by: Daniel Chaffelson <chaffelson@gmail.com> * Bump version: 0.18.0 → 0.19.0

Description
NiPyApi cannot create new Parameter Contexts in NiFi 1.16.0+ due to missing
inherited_parameter_contextsfield (not defaulted in NiFi, although it probably should be - NIFI-9470.Suspect updating the create_parameter_context method to accept an optional
inherited_parameter_contextsparameters (defaulting to an emptylist) then sending that to NiFi as part of theParameterContextDTOwould be a solution - at least until NIFI-9470 is fixed, but actually NiPyApi should probably be updated to handle inherited parameter contexts now that they've been introduced.What I Did
Attempted to create a Parameter Context in a new instance of NiFi 1.16.1 by calling
nipyapi.parameters.create_parameter_context("local")Urgency
Cannot create Parameter Contexts with NiPyApi (or NiFi Toolkit as a workaround), which means automated deployments to NiFi 1.16.0+ (possibly 1.15.0+) where a Flow includes a Parameter Context is no longer possible.
That said, if the Parameter Context already exists in a Flow Definition within NiFi Registry, it can be imported then subsequently updated within NiFi (assuming that fits with one's deployment workflow).
