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.
