Picocli - Some expected errors lead to a stacktrace and they shouldn't

[gsmet]

In the case of quarkus config enc, if I forget the parameter, I end up with a stacktrace which is not really expected: we should have a standard Picocli error output and not a full stacktrace as this is a standard use case of the CLI and not an underlying error.

$ quarkus config enc
