Verify if cloning performs deep cloning

Check if cloning performs deep cloning and does not use the same reference

it seems like some of the pointers in the instance are not cloned. The same case goes for slices and maps. So we need a proper method to deeply clone everything.

type Instance struct {
	kubernetesService    *v1.Service
	builderFactory       *container.BuilderFactory
	kubernetesReplicaSet *appv1.ReplicaSet
	portsTCP             []int
	portsUDP             []int
	command              []string
	args                 []string
	env                  map[string]string
	volumes              []*k8s.Volume
	policyRules          []rbacv1.PolicyRule
	livenessProbe        *v1.Probe
	readinessProbe       *v1.Probe
	startupProbe         *v1.Probe
	obsyConfig           *ObsyConfig
}
