Christian Decker	9d4148ce68	pylightning: Warn users of plugins that may break due to extra args We recently noticed that the way we unpack the call arguments for hooks and notifications in pylightning breaks pretty quickly once you start changing the hook and notification params. If you add params they will not get mapped correctly causing the plugin to error out. This can be fixed by adding a `VAR_KEYWORD` argument to the calbacks, i.e., by adding a single `**kwargs` argument at the end of the signature. This commit adds a check that such a catch-all argument exists, and emits a warning if it doesn't. It also fixes up the plugins that we ship ourselves.

pylightning: Warn users of plugins that may break due to extra args

We recently noticed that the way we unpack the call arguments for hooks and
notifications in pylightning breaks pretty quickly once you start changing the
hook and notification params. If you add params they will not get mapped
correctly causing the plugin to error out.

This can be fixed by adding a `VAR_KEYWORD` argument to the calbacks, i.e., by
adding a single `**kwargs` argument at the end of the signature. This commit
adds a check that such a catch-all argument exists, and emits a warning if it
doesn't.

It also fixes up the plugins that we ship ourselves.

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

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.
