This means we can see the values in listconfigs, even if we haven't set
them yet.
In particular, we now see the following:
* autoclean-cycle.value_int=3600
* bitcoin-rpcclienttimeout.value_int=60
* bitcoin-retry-timeout.value_int=60
* funder-max-their-funding.value_str=4294967295sat
* funder-per-channel-min.value_str=10000sat
* funder-reserve-tank.value_str=0sat
* funder-fund-probability.value_int=100

We need to pass through setconfig in check mode, then we need to have libplugin
add (and use!) a `check_only` parameter to all option setting.

Changelog-Added: JSON-RPC: `check` `setconfig` on plugin options can now check the config value would be accepted.
I added a plugin arg and was surprised that compile didn't break.
This is because typesafe_cb et al are conditional casts: if the type
isn't as expected it has no effect, but we're passing plugin_option() through
varargs, so everything is accepted!
Add a noop inline to check type, and fix up the two cases where we
used `const char *` instead of `char *`.

When a request comes through, we forward it over to the funder who
uses the currently set policy to figure out how to handle it.
Includes small update to the policy engine which decides whether or not
to fund a request.
Changelog-Experimental: Plugins: `openchannel2` hook now includes optional fields for a channel lease request
Implement support for liquidity ads in `funder` plugin. We set the
command line options for the leases, as well as sending the updated ads
to lightningd (who then passes them through to gossipd)
Behold! An immaculately concepted plugin for configuring your node to do
amazing things*
