This adapts the test to the new 'plugin' command: no more sleeping,
since we are synchronous !
This tests the timeout by increasing the 'slowinit' plugin sleep
duration at init reception.
This adds a broken plugin to make sure we won't crash because of a
misbehaving plugin (unmet dependency is the most common case).
This has a slight side-effect of removing the actual begin and commit
statements from the `db_write` hooks, but they are mostly redundant anyway (no
harm in grouping pre-init statements into one transaction, and we know that
each post-init call is supposed to be wrapped anyway).

We seem to be getting intermittant failures, but it's hard
to disgnose. Simplify it by moving all the test logic into
the test itself, and making the plugin dumber. This means we'll
see exactly what the differences are if it fails again.

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.

We were having a few issues with malformed data in the past, so this time we
really check that stuff.

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.
I misunderstood the API, this ended up nesting a result inside the JSON-RPC
result.
No concerns about backwards compatibility since this is so new.

We should be able to pass UTF-8 strings to and from plugins without
python turning them into JSON-\u escapes.

We don't, but we should, like we do for normal RPC. However, I chose
to use function annotations, rather than names-ending-in-'msat'
because it's more Pythony.
