This commit adds betweenness centrality to the available node metrics.
Betweenness centrality is a per node centrality measure which for an
arbitrary node v equals to the sum of shortest paths going trough v
divided by the number of all shortest paths for for each vertex pair
k, s where k != s != v.
This commit adds the NodeMetric interface which will be used for all
graph metrics not directly part of the autopilot but are useful in
composite heuristics to drive autopilot decisions and improve node
scores.
These tests exercise the different ways of sweeping a commitment, so
we'll cover the modified scripts used for anchor commitments and
spending the anchor itself by both parties.

Fixes a subtle bug where the outer scope predErr was hidden when the
return value of findForceClosedChannel was stored in a newly
defined variable with the same name.
This commit changes the switch to only log an error if update_fail_htlc
comes in and closeCircuit returns ErrUnknownCircuit. Rationale
being that only settles should hit this code path, anything else
is a result of a link flap and should be treated as an error.
This commit modifies updateCommitTx to error with ErrLinkShuttingDown
when we try to send a ContractUpdate on the htlcUpdates chan and the
link has closed the quit chan. It also changes the order of the call
to ackDownStreamPackets and contract update call for consistency since
the packets should be acknowledged before the link goes down.
This commit changes the fallback in NextLocalHtlcIndex to
RemoteCommitment since the LocalHtlcIndex field lags behind
on the LocalCommitment. Without this bug fix, open circuits
would get prematurely trimmed, resulting in more erroneous
logs. A test case is included to check that the fix works.
The pending closing channels field was present to cover an edge case
where coperatively closed channels were closed before upgrade and
confirmed after the upgrade. This commit deprecates the field and adds
a warning log to cover these edge cases.
In this commit, we make the internal channel funding flow aware of
frozen channels. We also update the testSingleFunderReservationWorkflow
method to ensure that the created channels have the proper type bit set.
