90c5f9a051 funderupdate: add documentation, update some params
Documentation for the funderupdate command on the funder plugin.
Realized we were missing the "leases_only" in the output; also adds
'_msat' to msat denominated outputs so they're parsed correctly by our
python bindings (also matches our naming conventions)

Changelog-EXPERIMENTAL: funder: `funderupdate` command to view and update params for contributing our wallet funds to v2 channel openings. Provides params for enabling `option_will_fund`.

77d2c538b3 queryrates: make it dev-only
Since we now use 'compact_lease' to gate an open (if the rates have
changed, we fail), we no longer need to rely on query rates for figuring
things out, so we make it dev-only.

Changelog-Changed: JSON-API: queryrates is now developer only

70bf57d54b channel-lease: reject if we're not currently advertising liquidity
If there's no plugin currently in place, we simply won't return any
funding at all, in which case we'd expect them to handle however
they want. (our implementation would fail the open, as we only accept
opens that have at least as much as we've requested provided)

9431984cef funder_policy: set default to 0
As we move to advertising liquidity, set the default to not have any
fuzz. This means we won't randomly reject an offer to buy liquidity.

376e6f8bd1 dual-funding: update fee_step to be a feerate
Using a 'feestep' is more restrictive than you'd want, instead we
enforce that the next feerate must be at least 1/64th more than the
last, but put no upper limit on it

Includes update to lnprototest changes

67c03c02a0 pytest: speed up test_opening.py::test_funder_contribution_limits when !DEVELOPER
This test takes 695 seconds, because fundwallet waits for the wallet to
notice the tx, which takes 60 seconds if not DEVELOPER.  Do all the waiting
at once, and this speeds the test up to 153 seconds.

8cef2c17ad pytest: fix flake in test_v2_open_sigs_restart_while_dead
We didn't wait for the sendtx to complete before shutting down,
and hence timed out:

        l2.stop()
        bitcoind.generate_block(6)

3c87e1f338 test_v2_open_sigs_restart: dont mine blocks until funding tx in mempool
This was flaky because sometimes we'd generate blocks before the funding
transaction reached the mempool.

If we wait until it's in, it works as expected.

ef1e36efe5 mfc: check that we can retry when things go haywire
There's a version of this that keeps the PSBT in memory and does some
fancy addition/subtraction of unuseable parts for the v2's, however
it's much easier and simpler to simply error on the peer and re-start
from the very beginning.

This only works if we haven't gotten commitments from the peer yet (in
fact either method would only work if we haven't got commitments from
the peer yet), so if we've got commitments from them we simply mark them
as failed an go again.

In a perfect world, we'd remember what inputs we used last time, and
reuse those again on the re-attempt, which would pefectly guarantee both
that the failed opens (ones w/ commitments exchanged) would be canceled
after this completes (and we could re-try the failed again).

As it is, this is not perfect. It is, however, servicable.
