This switches the logging implementation from using the `log`-facade
to using the `tracing-subscriber` instead. This allows us to also tap
into the tracing instrumentation if desired, which was not possible
with `log`.
Changelog-Changed cln-plugin: The logging adapter now uses tracing-subscriber allowing the `tracing` ecosystem to be used. No format changes.
The `cln-plugin` can be used to create a plugin that registers
additional rpc-methods. However, it doesn't allow to specify the `usage`
of the command.
This change makes it possible to specify the `usage`. It should not
contain any breaking changes.
I've opted to add a new method called `rpcmethod_from_builder` to the
`Builder` struct. This approach allows us to add new parameters in the
future.

Changelog-Deprecated: JSON-RPC: `listchannels` listing private channels: use listpeerchannels
This breaks our tests a bit, which assumed we can always see ourselves
even if we don't have a proper channel.
Usually we would deprecate this first, but it's unlikely to break
anyone since it's a bit obscure that this worked at all.

Changelog-Changed: JSON-RPC: `listnodes` no longer shows private (peer) nodes: use listpeers
We temporarily use a second gossmap so we can just switch private info off
for listincoming and not listchannels.
Note that listchannels now uses the local alias (if no scid), so we have
to change that in the routehint caller.
Since we now *always* use a channel alias in hints if one exists, a
test broke, so fix that.

We have a global JSON encoder hack, which means that any field ending in msat gets special treatment (so we can safely talk to lightningd, even if a field expects satoshi amounts, we are explicit). However, requests uses the JSON parser and DOES NOT want this conversion when sending it out as an HTTP response!
The simplest local fix we could find was Shahana's suggestion to iterate and covert away from Millisatoshi(): the reverse of what our JSON encoder does.

When we got our peer's sigs, if we were the remote, we would re-notify
the plugin, which in turn would re-send the tx-sigs to use.
In the case of CLN, we'd then
- break, because we'd re-forward the sigs to the `openchannel` plugin,
which was then in the wrong state (MULTIFUNDCHANNEL_SIGNED)
spenderp: plugins/spender/openchannel.c:598: json_peer_sigs: Assertion `dest->state == MULTIFUNDCHANNEL_SECURED' failed.
spenderp: FATAL SIGNAL 6 (version 5880d59-modded)
In the case of eclair, they'd just see our 2nd TX_SIGS message and
@t-bast would complain:
> This test works, with one minor issue: on reconnection, cln sends its tx_signatures twice (duplicate?).
This commit does two things:
- has the openchannel / spender plugin log a broken instead of
crashing when the state is not what we're expecting
- stops us from calling the `funder` plugin if this is a
replay/second receipt of commit-sigs.
- certificate generation
- config options validation
- log level from 'error' to 'info'
- sending method as None instead ""
- added `listclnrest-notifications` for websocket server rune method
Changelog-Fixed: websocket server notifications are available with
restriction of `readonly` runes
This functionality already exists in the Python framework; this feature
enables it for Rust plugins as well.
Changelog-Added: cln-plugin: Implement send_custom_notification to allow sending custom notifications to other plugins.
Under some circumstances we may want to not log to `lightningd`
directly, but rather configure the logging ourselves. This is useful
for example if we want to use `tracing` and `tracing-subscriber` to
add custom handling, or add opentelemetry span tracing.
Changelog-Changed: cln-plugin: Suppress internal logging handler via `with_logging(false)`
The tests will wait until it's locally enabled, but it might not have
the update in the gossip store. So have renepay enhance its local
view even if it already knows about the channel (this is correct
anyway, it just isn't very important usually).

This makes it easier to use outside simple subds, and now lightningd can

Even after migrating from pip install to poetry install for clnrest,
we still need to keep `plugins/clnrest/requirements.txt` for Fedora-28-amd64
build. `Dockerfile.builder.fedora` does not have poetry and will need
requirements.txt to install libraries with pip.
It is also required for non-developers who want to build cln from a tagged or master version.
Also requires us to expose memleak when !DEVELOPER, however we only
ever used the memleak tracking when the LIGHTNINGD_DEV_MEMLEAK
environment variable was set, so keep that.

This was a misunderstanding: nodeid is useful for commando, where it's the
peer's nodeid, and Noise-XK guarantees that we know who that is. It's

is redundant).

OpenAPI readme always includes `content-type: application/json` header, even when body parameters are empty.
But the server expects data if the content-type has been sent.
This results in a "Server Error" response for non-param requests from readme doc.
This only affects readme requests as it is designed to send the header by default.
