Add Intelligent Suggesting Command Correction

[kevwilliams]

When a user makes a datumctl get request and does not provide context the error message that responds is not informative enough to tell the user to change their approach.

datumctl get backends results in

Error from server (Forbidden): backends.gateway.envoyproxy.io is forbidden: User "kwilliams@datum.net" cannot list resource "backends" in API group "gateway.envoyproxy.io" in the namespace "default"`

This could be augmented to have a suggestion, in this case when the user does not provide a --project, or --organization the command is attempting to access things outside of the reach of the user. We could add this information to the error message to help the user realize that they need to be more specific in their request or provide that information to the user when they run the command "Try running --project or --organization to improve your results"

Hello @kevwilliams ! Thank you for your suggestion. I agree, it makes a lot of sense, the error should be actionable and informative. What you proposed is a lot better.

Cobra has should have an error handling function we can use to remap errors and expand them, since we use kubectl as library a lot happens there and it is a bit of a nightmare to change the code inside the command, so we need to work around it.

For your specific situation it is caused by a missing feature we are thinking about how to implement that works a bit like context in Kubernetes where you specify the server, namespace you want to interact with and the CLI,sdk reads from there if it does not know what to do. We need to do something similar but for project and organization so you will always have a default set to those to rely on. datum-cloud/enhancements#582
