Adding the active kubecontext to minikube profile list command

The minikube profile list does not show the active kubecontext. The active kubecontext was added to the profiles as ActiveKubeContext similar to the Active property of the existing implementation. This allows older version, which rely on the json field Active, to still work and additionally obtain the information about ActiveKubeContext. The table representation for the minikube profile list command was updated as well. Active minikube profiles are highlighted in the Profile column. The Active column was replaced with an Active Kubecontext column.
