Error whitout user meaning when run kubectl kudo get instances before init

[camilamacedo86]

What happened:
After install, I run kubectl kudo get instances

$ kubectl kudo get instances
Error: creating kudo client: operators: customresourcedefinitions.apiextensions.k8s.io "operators.kudo.dev" not found

What you expected to happen:
Not show an error without user meaning. It could provide a friendly message telling that I should run kubectl kudo init in order to have instances.

How to reproduce it (as minimally and precisely as possible):

• New installation, and then run the command.

What I see as a solution here is to do some validation before actually creating a client and make sure that the cluster is initialized. Potentially we would want to have that check before many other commands because most of them expect the server to be initialized.
