Since the code for creating and using a macaroon service is the same for
multiple projects (pool, loop, faraday & litd), the code has been
unified in lndclient. So this commit removes the macaroon service code
and instead uses the lndclient code.
Since the default key for the macaroon db is now a shared secret with
LND, faraday requires LND's admin macaroon so that this secret can be
derived. So this commit also updates all references of LND's `readme`
macaroon to the `admin` macaroon.
Fixes#84.
Allows faraday to only use the readonly.macaroon (or a custom baked one)
to connect to lnd instead of needing to copy all macaroons (including
the subserver ones).
Consensue on the team is that nodereport is more representative of
a report about the node's operation than an accounting report. Renaming
in anticipation of upcoming release.
We are going to need the walletkit and chainnotifier subservers in
future changes, so we make the switch now. Note that this commit does
not build, and is split up for the sake of easy review.
