Separate options for pride do to ignore errors and to fail late

Right now there is a `pride do --ignore-errors` option that does just that: if there's an error, we continue working on the next module, and we don't show anything in the process's exit value.

We'd need a `--fail-late` option as well, i.e. when there's an error, we should continue with the next module, but in the end provide a list of modules with errors, and also change the exit value.
