This change only implements pytest hooks when we know pytest_json_report plugin has
been loaded. Previously, the hooks were being loaded before plugin, thus causing errors
cause(pytest_sessionfinish needs the plugin to function).

* Added pytest-json-report plugin
	- modifying app-opts in setup.cfg
	- adding hook to all conftest.py files in repo
	- setting report to be saved to test_root/log/warnings.json
	- Writing custom logic to save json report to avoid overwrite if pytest called twice
This was created to allow us to easily parse through test warnings in jenkins

This will remove imports from __future__ that are no longer needed.
