Some tests need to inspect it, but most don't, and I suspect I'm missing some
error messages due to this.

The CLN API is rather strict about the fact that we should skip
providing a field whenever it is empty. Checking for `is_none` would
still include empty arrays.
Changelog-Fixed cln-rpc: Optional empty arrays will no longer be serialized in requests
This allows us to re-use existing tests (assuming the call and fields
are covered by `cln-rpc` and `cln-grpc`) to test the full roundtrip
from test over the grpc interface to the json-rpc interface and back
again.
You can switch to the grpc interface by setting the `CLN_TEST_GRPC`
environment variable to 1, but for now only very few shims are
implemented (due to the non-generated nature of LightningRpc).
To test the grpc interface we'll want to emulate the JSON-RPC
interface as best we can, hence when talking to the grpc interface we
want to convert back into a parsed JSON format as LightningRpc would
have returned it. This is just the simplest way of closing the loop
here:
```
pyln-testing --grpc-> cln-grpc --grpc2json
^ |
| v
| JSON-RPC
| |
TEST v
^ CLN
| |
| v
pyln-testing <-grpc2py-- cln-grpc <- json2grpc
```
These may eventually end up in pyln-client, as they allow talking to
the GRPC interface exposed by cln-grpc, however for now they are used
for testing only. Once we have sufficient API and test coverage we can
move them and leave imports in their place.
We were overriding the name right when loading, which is bad since in
some languages we use the method name as tag in the requests, thus
renaming causes us to call something that isn't defined.
Changelog-Fixed: cln-rpc: Fixed a naming mismatch for `ConnectPeer` causing `connectpeer` to be called on the JSON-RPC
This was introduced to allow creating a shared secret, but it's better to use
makesecret which creates unique secrets. getsharedsecret being a generic ECDH
function allows the caller to initiate conversations as if it was us; this
is generally OK, since we don't allow untrusted API access, but the commando
plugin had to blacklist this for read-only runes explicitly.
Since @ZmnSCPxj never ended up using this after introducing it, simply
remove it.

Changelog-Removed: JSONRPC: `getsharedsecret` API: use `makesecret`
This has been replaced with better rust bindings that can then be
consumed via pyo3, consolidating the C interface in a portable
wrapper.
Changelog-Removed: libhsmd: Removed the `libhsmd_python` wrapper as it was unused
Since we now log directly, we don't prepend the prefix ourselves, making it really
hard to tell *which* lightningd the log applies to!

routing.c now flags rate-limited gossip as it enters the gossip_store but
makes use of it in updating the routing graph. Flagged gossip is not
rebroadcast to gossip peers.
Changelog-Changed: gossipd: now accepts spam gossip, but squelches it for
peers.
This will be used to decouple internal use of gossip from what is
passed to gossip peers. Updates GOSSIP_STORE_VERION to 10.
Changelog-Changed: gossip_store updated to version 10.
I had to parse quite a few of these files debugging zeroconf, so I
thought it might be nice to have direct access here.
Changelog-Added: pyln-testing: Added utilities to read and parse `gossip_store` file for nodes.
This will eventually enable us to specify 0 for zeroconf channels.
Changelog-Added: JSON-RPC: Added `mindepth` argument to specify the number of confirmations we require for `fundchannel` and `multifundchannel`
Ok this should be fixed the following stack trace

Even though we generally wait until a node has seen the gossip,
that doesn't mean that connectd has processed it! This means when
we connect it may still send us "old" gossip.
So we set the OPT_GOSSIP_QUERIES bit, which means don't send until we
ask. But now it sends us WIRE_QUERY_CHANNEL_RANGE, so everyone needs
to filter that out.

I saw another "only_one()" fail on alias checking: it's not
entirely clear to me with the more aggressive sending of
own gossip, that we necessarily process in order, so we might
not have actually seen all channels just because we saw
the farthest one.

Get it to log direct to stdout, so we see what's happening *as it
happens* rather than as we read it. We could restore the thread we
were using before, but that added more problems than it solved.
This means that we need the hsm password prompts in the log though.

Some flakes are caused by weird races in this code. Plus, if we
get things to write straight to files, we might see things in
there on post-mortem which happen after the python runner exits.
It's a bit less efficient, but much simpler. Let's see if it helps!
Some tests need a rework now, since we don't get a failure (except
eventual timeout), but they're simpler.

We use ephemeral_port_reserve to grab ports, but this can fail when we
restart a node, since the port can be reallocated at that point.
Attempt to overcome this using a global reserved list (is there a
neater way?).

This happens under CI, but it's not informative. Sleep and retry.
Also, "except (OSError, Exception)" does not seem to do what you'd think:
this clause never gets run.

Over time, it has cost us more developer cycles than it has gained.
It has hidden intermittant bugs, and allowed cruft to accumulate:
when we eventually tried to figure out what was going wrong, the
actual change which caused it was now stale and forgotten.
This was a particular bane during the connectd rewrite, and I
worked through some issues which had occurred before, but were not
more likely.

So this was quite a journey:
- We want relative depdendencies (using the `path` argument) whenever
developing locally. Otherwise we would have to install each
dependency every time we change a single character, which
undoubtedly would cause us to waste time trying to debug an issue
just because we forgot to install.
- When publishing however we want to rely on the version number,
since the repo context gets lost upon publishing, and path
dependencies cause failures.
The solution then it seems is to use `dev-dependencies` (not that
surprising once you find it) with relative paths, so that `poetry
install` uses these over the normal dependencies (no idea how they
dedup them) and use `dependencies` when publishing. The paths are
still in there when publishing, but `pip install` ignores them.
I checked that `poetry install` from an unrelated project doesn't
accidentally use the path dependencies, even when adding them as
dev-dependencies. This should hopefully also allow installing them
as a repo link, though I can't test that right now.
We should be using amount_msat always. Many tests were not. Plus,
deprecating it simplifies the code.

Changelog-Deprecated: JSONRPC: `sendpay` `route` elements `msatoshi` (use `amount_msat`)
This prepares for when they start being u64, not strings with msat appended.
This has a strange side effect on our schema: despite the name,
decodepay's `fee_base_msat` is actually a u64, which we now convert to
msat on decode.

This is consistent with our output changes, and increases consistency.
It also keeps future sanity checks happy, that we only use JSON msat
helpers with '_msat' fields.

Switching to poetry, and deprecating python 3.6, made things a bit
more tricky. Sadly we'll not be able to build jammy, as its support is
missing in the tag tarball, but it'll be there for the next release.
