Add ShardingSphereChaos CRD and convert chaos to Chaos Mesh logic in Reconcile function

[moomman]

1. Add basic convert type: Selector,Pod Chaos,Network Chaos,WorkFlow.
2. Add convert functions in Controller.Add convert and create chaos logic in Reconcile function.
3. Add ChaoKind Enums

I have tested it usage in kubenetes environment.It works well As expected.

Need add unit test with ginkgo.

you can use fakeClient to mock client.Client. below is a simple example.

import (
        // import other needed packages...
        appsv1 "k8s.io/api/apps/v1"
	corev1 "k8s.io/api/core/v1"
	"k8s.io/apimachinery/pkg/runtime"
	"sigs.k8s.io/controller-runtime/pkg/client"
	"sigs.k8s.io/controller-runtime/pkg/client/fake"
)

var fakeClient client.Client
// your new reconciler or controller
var reconciler *YourReconciler

// register some CRD or resources for your need.
scheme := runtime.NewScheme()
Expect(corev1.AddToScheme(scheme)).To(Succeed())
Expect(appsv1.AddToScheme(scheme)).To(Succeed())
fakeClient = fake.NewClientBuilder().WithScheme(scheme).Build()
reconciler = &controllers.YourController{}
req := reconcile.Request{
			NamespacedName: client.ObjectKey{
				Namespace: "test-namespace",
				Name:      "test-resource",
			},
		}

// create some resource if needed by fakeClient.Create()
// Expect(fakeClient.Create(context.Background(), &appsv1.Deployment{})).To(Succeed())
// ...

res, err := reconciler.Reconcile(context.Background(), req)
Expect(err).NotTo(HaveOccurred())
// handle res if needed.
// ...

you can move some common code to ginkgo's BeforeEach and AfterEach. Please help yourself.
