  3. build: apply rpctest tag in itest 

    We need to distinguish an lnd build for the purpose of integration
testing from a regular dev build. This makes it possible to adapt
parameters to let integration tests run faster (for example:
sweeper batch window).

  6. sweep+utxonursery+cnct+breacharbiter: add height hint to input 

    This commit is a preparation for the implementation of remote spend
detection. Remote spends may happen before we broadcast our own sweep
tx. This calls for accurate height hints.

  9. sweep: add sweeper store 

    This commit adds a store for the sweeper. The sweeper needs minimal
persistent data to be able to recognize its own sweeps.

  10. sweep: add time-based sweeper 

    In this commit, the sweep package is extended from just tx generation to
an active sweeper that collects sweep inputs and autonomously proceeds
to publish the sweep tx after the batch window time interval has passed
without new inputs being added.

  12. utxonursery: connect to time-based sweeper 

    Previously, nursery generated and published its own sweep txes. It
stored the sweep tx in nursery_store to prevent a new tx with a new
sweep address from being generated on restart.

In this commit, sweep generation and publication is removed from nursery
and delegated to the sweeper. Also the confirmation notification is
received from the sweeper.
