Feature request description 

When the user's session end the related token that is already injected inside the KUBECONFIG end too, when this case happens the user need to go back to the dashboard and restart the env for the token to be updated (has he can't do it from the ide)

The solution would be : 

Each time the user connect/reconnect the injectKubeconfig function should be called to prevent the need of a restart, for example during a long task.
