sweep: update storeRecord to include utxo index
In this commit, we complete a recently added feature by ensuring that
even if we go through the RBF loop to create a txn, that we still
populate the `outpointToIndex` map. Unit tests have been updated to
ensure this is always set as expected.

sweep: add new AuxSweeper interface
In this commit, we add a new AuxSweeper interface. This'll take a set of
inputs, and a change addr for the sweep transaction, then optionally
return a new sweep output to be added to the sweep transaction.

We also add a new NotifyBroadcast method.  This'll be used to notify
that we're _about_ to broadcast a sweeping transaction. The set of
inputs is passed in, which allows the caller to prepare for the ultimate
broadcast of the sweeping transaction.

We also add ExtraTxOut to BumpRequest pass fees to NotifyBroadcast. This
allows the callee to know the total fee of the sweeping transaction.

sweep: catch third party spent in fee bumper for neutrino
This commit adds a new check for neutrino backend - when the inputs in
the sweeping tx are spent by a third party, we will send back a
`TxFailed` event to free the rest of the inputs for re-grouping.

sweep: make sure max fee rate can be reached
Previously we don't allow confTarget to be 0, which ended up the final
position being never reached. We fix it here by allowing confTarget to
be 0 in case the deadline has already been passed for a given input.

sweep: add a dedicated method to create sweeping txns
This takes the old `createSweepTx` and refactors it to be
sweep-specific. A sweeping txns differs from a normal tx as it doesn't
need to take outputs as params.

So these inputs can be retried by the sweeper.

sweep: add monitor loop to TxPublisher
This commit finishes the implementation of `TxPublisher` by adding the
monitor process. Whenever a new block arrives, the publisher will check
all its monitored records and attempt fee bumping them if necessary.

lnwallet+sweep: introduce TxPublisher to handle fee bump
This commit adds `TxPublisher` which implements `Bumper` interface. This
is part one of the implementation that focuses on implementing the
`Broadcast` method which guarantees a tx can be published with
RBF-compliant. It does so by leveraging the `testmempoolaccept` API,
keep increasing the fee rate until an RBF-compliant tx is made and
broadcasts it.

This tx will then be monitored by the `TxPublisher` and in the following
commit, the monitoring process will be added.

lnwallet+sweep: calculate max allowed feerate on BumpResult
This commit adds the method `MaxFeeRateAllowed` to calculate the max fee
rate. The caller may specify a large MaxFeeRate value, which cannot be
cover by the budget. In that case, we default to use the max feerate
calculated using `budget/weight`.

sweep: introduce Bumper interface to handle RBF
This commit adds a new interface, `Bumper`, to handle RBF for a given
input set. It's responsible for creating the sweeping tx using the input
set, and monitors its confirmation status to decide whether a RBF should
be attempted or not.

We leave implementation details to future commits, and focus on mounting
this `Bumper` interface to our sweeper in this commit.
