Fix testenv readiness checks

[ramizpolic]

Description

The readiness check for services can report ready behaviour even when all the services are not ready.

Expected Behavior

Ready returns true iff all services are ready.

Actual Behavior

Ready can be true when last service is ready, unrelated to the state of the previous service.

Steps to Reproduce

vmclarity/testenv/kubernetes/kubernetes.go

Lines 71 to 94 in c688a55

	func (e *KubernetesEnv) ServicesReady(ctx context.Context) (bool, error) {
	logger := utils.GetLoggerFromContextOrDiscard(ctx).WithFields(e.meta)
	services, err := e.Services(ctx)
	if err != nil {
	return false, fmt.Errorf("failed to retrieve list of services: %w", err)
	}
	var result bool
	for _, service := range services {
	logger.Debugf("checking service readiness. Service=%s State=%s", service.GetID(), service.GetState())
	switch service.GetState() {
	case envtypes.ServiceStateReady, envtypes.ServiceStateDegraded:
	result = true
	case envtypes.ServiceStateNotReady, envtypes.ServiceStateUnknown:
	fallthrough
	default:
	result = false
	}
	}
	return result, nil
	}
