As the comment in set_feerates says: "Technically, this waits until
it's called, not until it's processed.".
And the wait_for() line doesn't work, since that condition is already true.

On fast machines, we don't get failures sometimes on commando commands.
(*But* we still got "New cmd replacing old" messages, which is how I
realized we weren't freeing them promptly, hence the previous fix).

This was weird. Here is the message (with \n turned into real new lines):
```

Finally, I realized that we *kill* l2: this means it has updated the
plugin db but not the real db. This is expected: a real backup plugin
would handle this case.
Simply disable the test for this case.

I wondered how `tests/plugins/dblog.py` worked, since it is supposed to fail
unless the `dblog-file` arg is set:
```
@plugin.init()
def init(configuration, options, plugin):
if not plugin.get_option('dblog-file'):
raise RpcError("No dblog-file specified")
```
But it was set to "null". That's because 'None' in python is turned into a literal
JSON "null", and we take that as the default value.
We also cleanup the popt->description double-assignment (a leftover
from when this was optional).

Changelog-Fixed: plugins: setting the default value of a parameter to `null` is the same as not setting it (pyln plugins did this!).
As we'll see in the next patch, this wasn't *supposed* to work wihtout dblog-file,
but it did, creating a dblog called "null".

Don't log_io final messages twice (multiplex_final_message already does
this, so it's confusing to see us send e.g. WIRE_ERROR twice!).
And report that the peer has failed to connect out *before* telling
lightningd, otherwise we get a very confusing ordering, e.g.:

If rune contains invalid UTF-8, offers (which implements decode) would
produce JSON with invalid UTF-8, which causes lightningd to complain
and kill it, and then die because it's an important plugin.
So don't decode invalid UTF-8!

would fail when we try to run the tests).

We were waiting too long for the reconnect to happen (60s default),
which caused this test to timeout.
When testing, let's speed up the reconnect.
L2 tried to reconnect but didn't have connection information in its
gossip -- is there a way to ask/save connection data from a node you're
making a channel with that doesn't rely on their node_announcement?
This gives a nice way to ensure your secret is the correct one.
Also, we don't need to suppress VALGRIND for this test, now the output
races are fixed.

1. fromwire now allocates TLVs, so this was actually a leak.
2. We can simply hand "NULL" to towire_, since that is the same as
this empty tlv.

This is usually a signal that lightningd is shutting down, so notify
any instance that is waiting on `plugin.join()`.
Changelog-Fixed: cln-plugin: Fixed an issue where plugins would hang indefinitely despite `lightningd` closing the connection
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
