In this commit we restore the prior workflow of the docker-compose set
up with have to allow developers to quickly erect an lnd+btcd instance.
In a recent change, we now prompt the user for a passphrase that will
be used to encrypt the wallet database. This affected the prior
workflow, as it assumed set up was non-interactive.
In this commit we restore the prior behavior as we now start the lnd
nodes with --noencryptwallet.
In this commit, we fix a lingering issue in the execution
of the lnd container, after the new macaroon based
authentication was added. With the new authentication
feature, if the datadir was changed, but `lncli` wasn't
updated to point to the macaroon path, then none of
the commands would work.
To fix this, we simply omit setting the data directory.
