pytest: Add a test for the 'warning' subscription and notification

Browse Source 
1. Create a plugin: ./lightning/tests/plugins/pretend_badlog.py
This plugin subscribes 'warning' notification and log the payload of
'warning';
2. Add a new test: tests/test_plugin.py::test_warning_notification
This test runs the plugin-pretend_badlog.py and check if 'warning'
notification can be normal triggered and subscribed.
