All the core notifications changed over to wrapping the notification
fields in an object with the name of the notification, but notifications
from plugins were missed.
Changelog-Added: Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notifications now have objects of the same name containing the expected fields.
Changelog-Deprecated: Plugins: `channel_hint_update`, `pay_failure` and `pay_success` notification fields outside the same-named object.

Rather than forcing them to wrap their parameters in a "payload"
sub-object, copy in params directly. We include the "origin" field
one level up, if they care.
The next patch restores compatibility for the one place we currently use
them, which is the pay plugin.

Changelog-Deprecated: pyln-client: plugin custom notifications origins and payload (use parameters directly)
For older lightningd, we copy field into the raw dict, for newer we recreate the old
"payload" member.
We do fix up the custom_notification test which set params to a string instead of a dict:
that's just weird!
We also change the hacky parsing to proper dict extraction.

Changelog-Changed: pyln-client: plugin notifications parameters now exposed directly, not wrapped in `params` object.
Since plugins will start sending them soon, and they are likely to get
it wrong sometimes, be a bit more lenient, warn them in the logs
instead and then make sure it doesn't accidentally work anyway.
We will eventually start emitting and dispatching custom notifications
from plugins just like we dispatch internal notifications. In order to
get reasonable error messages we need to make sure that the topics
plugins are asking for were correctly registered. When doing this we
don't really care about whether the plugin that registered the
notification is still alive or not (it might have died, but
subscribers should stay up and running), so we keep a list of all
topics attached to the `struct plugins` which gathers global plugin
information.
