* refactor(kubernetes): keep Provider as only external Kubernetes interface Initial phase to unify-merge the Provider interface with the Manager struct. - Renamed ManagerProvider to Provider (i.e. kubernets.Provider) - Moved Manager related logic to specific files - Exposed relevant method through Provider interface (GetDerivedKubernetes, IsOpenShift, VerifyToken) Signed-off-by: Marc Nuri <marc@marcnuri.com> * Update pkg/kubernetes/provider_kubeconfig.go Co-authored-by: Calum Murray <cmurray@redhat.com> Signed-off-by: Marc Nuri <marc@marcnuri.com> --------- Signed-off-by: Marc Nuri <marc@marcnuri.com> Co-authored-by: Calum Murray <cmurray@redhat.com>
