tests/taler: init basic test

Test build and services start, but libeufin-bank fails when trying to
access the database to change the admin's password.

We need to execute the command as the libeufin-bank user.

tests/taler: add master private key

tests/taler: rewrite `register_bank_account` to Nix

tests/taler: rename libeufin node to bank

tests/taler: use xtaler wire_type instead of iban

tests/taler: remove redundant data from conf files

tests/taler: enable exchange account

tests/taler: remove unused talerConfig

tests/taler: add client node and attempt a withdrawal

tests/taler: systemd_run optional user and group args

tests/taler: refactor and make a withdrawal

tests/taler: refactor tasks into subtests

tests/taler: properly read and test balance

tests/taler: refactor commands and add comments

nixos/taler: rename private key

tests/taler: enable nexus service in bank node

tests/taler: nexus fake incoming payment test

tests/taler: use correct path for nexus client keys

tests/taler: add merchant node

tests/taler: merchant register instance

tests/taler: init pay for order merchant

tests/taler: fix payto uri

tests/taler: withdraw smaller amount

This makes the test faster

tests/taler: verify balance

tests/nixos: debugging merchant payment, cleanup

tests/taler: fix libeufin command, use curl to register accounts

tests/taler: add basic online test

tests/taler: move nodes into separate directory

tests/taler: fix insufficient balance error

Turns out that the exchange wire fees need to be set up (even if they're
0) in order for the CLI wallet to deposit coins into the merchant's bank
account.

tests/taler: improve node importing, port forwarding

tests/taler: import scripts from a separate file

tests/taler: move tests into a sub-directory

tests/taler: manually start services, cleanup

This results in less overhead and conflict since components will not try
to prematurely connect to the ones that haven't finished their set up.

tests/taler: remove online test

This was used to debug the insufficient balance problem, but it's not
really that useful by itself.

tests/taler: add nexus keys

tests/taler: use bank initalAccounts option

taler/tests: use initialAccount

tests/taler: make nexus work

tests/taler: don't run nexus test if there is no internet

tests/taler: use openFirewall, remove manual package install

fix(test): evaluation errors

fix(test): create nexus role by enabling createLocalDatabase
