[Bug] 'eksctl create podidentityassociation' does not work in the case of EKS auto-mode

[TarmoKople]

eksctl does not check whether EKS is using auto-mode or not. In EKS auto-mode, there is no need to check whether the eks-pod-identity-agent is installed or not, because eks-pod-identity-agent is part of the EKS auto-mode.

What were you trying to accomplish?

I tried to create a new podidentityassociation.

eksctl create podidentityassociation  ..... 

What happened?

Error: the "eks-pod-identity-agent" addon must be installed to create pod identity associations; please enable it using `eksctl ....

How to reproduce it?

Run again

eksctl create podidentityassociation  ..... 

Logs

Anything else we need to know?

The IsPodIdentityAgentInstalled function in the file pkg/actions/podidentityassociation/migrator.go does not check whether EKS is using auto-mode or not.

So for eks auto-mode a new cluster can be created with auto-mode or it can be enabled for an existing cluster. as far as I understand the computeConfig flag here tells whether a cluster has auto-mode enabled or not. if we do not have to rely on the eksctl ClusterConfig then we can do a describe-cluster to get the flag to decide if it is in auto-mode or not. Otherwise if we can be sure that ClusterConfig will always have updated information then we do not need to make that describe-cluster call to determine if auto-mode is enabled or not.
