cln-plugin throws away the "configuration" field from the "init" message.

Added a unittest as separate commit to make sure the "init" message (used this example) can be parsed. Not sure if this is helpful or not.

If we keep this struct, what else should go in it?

overall LGTM, just take a decision if we want use an HasMap or a Struct for the configuration

As you mentioned above making these things we have control over as strongly typed as possible would be a good idea. So I'd vote in favor of the Configuration struct 👍

Added the rest of the fields to Configuration mostly copying from rust-clightning-rpc as suggested by @vincenzopalazzo. I prefer the strongly typed struct too.

It is missing the Changelog in the body commit, maybe Changelog-Added: cln_plugin: take into consideration the cln configuration from init msg can be a good description?

The tests seem to be failing because this match is failing with my Configuration struct. But AFAIKT my unittest does exactly the same match and it works.

In my unittest I'm using exactly this JSON and it passes. Why is it failing in the python test in CI?

It does seem that the example JSON in the link above is different from what the CI test is sending. For example, the always_use_proxy value, for example, is missing in CI.

cln-plugin: Make the proxy-related configuration Option<>

These are only populated if a proxy was specified, see
lightningd/plugin.c:1855, so we were getting upset when we expected
them and they weren't set.
