Add more remote vlan examples (#4433)

- The existing suite was broken into two parts:
  - internal
  - vlan breaktrough
- Added OVS-forwarder example
- Added multiple NS example

 # NSM Remote Vlan Examples
 
-This setup can be used to check remote vlan mechanism. Contain basic setup for NSM that includes `nsmgr`, `registry-k8s`, `admission-webhook-k8s`, `nse-remote-vlan`. The `nse-remote-vlan` belongs to the nsm-system since does not have role in data-plane connection.
+This setup can be used to check remote vlan mechanism with both OVS and VPP forwarder. Contain basic setup for NSM that includes `nsmgr`, `registry-k8s`, `admission-webhook-k8s`, `nse-remote-vlan`. The `nse-remote-vlan` belongs to the nsm-system since does not have role in data-plane connection.
 
 ## Requires
 
 - [spire](../spire)
 
 ## Includes
 
+- [Remote VLAN mechanism using forwarder-ovs](./rvlanovs)
 - [Remote VLAN mechanism using forwarder-vpp](./rvlanvpp)
 
 ## Run
 
-1. Create secondary bridge network and connect kind-worker nodes:
-
-    ```bash
-    docker network create bridge-2
-    docker network connect bridge-2 kind-worker
-    docker network connect bridge-2 kind-worker2
-    ```
-
-2. Rename the newly generated interface to eth1 in both kind-workers:
-
-    ```bash
-    ifw1=$(echo $(docker exec kind-worker ip link | tail -2 | head -1) | cut -f1 -d"@" | cut -f2 -d" ")
-    docker exec kind-worker ip link set $ifw1 down
-    docker exec kind-worker ip link set $ifw1 name eth1
-    docker exec kind-worker ip link set eth1 up
-    ifw2=$(echo $(docker exec kind-worker2 ip link | tail -2 | head -1) | cut -f1 -d"@" | cut -f2 -d" ")
-    docker exec kind-worker2 ip link set $ifw2 down
-    docker exec kind-worker2 ip link set $ifw2 name eth1
-    docker exec kind-worker2 ip link set eth1 up
-    ```
-
-3. Create ns for deployments:
-
-    ```bash
-    kubectl create ns nsm-system
-    ```
-
-4. Apply NSM resources for basic tests:
-
-    ```bash
-    kubectl apply -k .
-    ```
-
-5. Wait for NSE application:
-
-    ```bash
-    kubectl -n nsm-system wait --for=condition=ready --timeout=2m pod -l app=nse-remote-vlan
-    ```
-
-6. Wait for admission-webhook-k8s:
-
-    ```bash
-    WH=$(kubectl get pods -l app=admission-webhook-k8s -n nsm-system --template '{{range .items}}{{.metadata.name}}{{"\n"}}{{end}}')
-    kubectl wait --for=condition=ready --timeout=1m pod ${WH} -n nsm-system
