CLI testing

[juan518munoz]

Implement CLI testing following this guide with escargot to use select features.

test_cli_create_account_works hangs if the database is clean, testing seems to work only if the command is ran manually at least once before running the test.

It would be nice to know why the tests hang if there is a clean DB. Maybe because both commands are executed and they lock on table creation? I think it's possible to make them run sequentially with the crate serial_test (although we don't want to use that besides just testing this problem). An alternative is to run tests with --test-threads 1 although this only reduces concurrency.

As we discussed offline, if it's easy to work around, let's try to remove crates or try to make sure they are no_std compatible. If there is no good alternative, it's fine to add them for now.

assert_cmd doesn't support running with features, using escargot seems mandatory, nevertheless, it is no std compatible.

Testing further (being more patient) I've found thath it doesn't really hang, it just takes about a minute to complete, running with a limited thread count takes the same amount of time.
