To make it possible to refresh Kubernetes clusters responsible all
places that used ClusterDetails[] before now use the
KubernetesClustersSupplier directly and call getClusters() on it. This
allows people to use implement custom KubernetesClustersSuppliers that
fetch the clusters from somewhere and refresh them using whatever
mechanism they might need.
