A user not knowing how Kestra work has no way to understand what's going on, this is usually due to missing configuration so we should detect this and points to the correct configuration guide.

We should check preconditions on all Kestra server commands and display a nice error message for the common cause of misconfiguration that is missing queue, repository or storage configuration.
