Add dashboard for NodeLatencyMonitor feature

[antoninbas]

Antrea v2.1 introduced the NodeLatencyMonitor feature, which provides an API reporting inter-Node latency measurements in a K8s cluster.
For example:

kubectl get nodelatencystats/kind-worker -o yaml

apiVersion: stats.antrea.io/v1alpha1
kind: NodeLatencyStats
metadata:
  creationTimestamp: null
  name: kind-worker
peerNodeLatencyStats:
- nodeName: kind-control-plane
  targetIPLatencyStats:
  - lastMeasuredRTTNanoseconds: 5837000
    lastRecvTime: "2024-07-26T22:40:03Z"
    lastSendTime: "2024-07-26T22:40:33Z"
    targetIP: 10.10.0.1
- nodeName: kind-worker2
  targetIPLatencyStats:
  - lastMeasuredRTTNanoseconds: 4704000
    lastRecvTime: "2024-07-26T22:40:03Z"
    lastSendTime: "2024-07-26T22:40:33Z"
    targetIP: 10.10.2.1

(Performing a List operation on all NodeLatencyStats resources will return the latency information reported by each individual Node)

This information should be displayed in antrea-ui, via a dedicated dashboard.
The dashboard should be able to handle small (<10 Nodes) and very large (1,000 Nodes) clusters gracefully.
Maybe something similar to the ping mesh visualization dashboard developed by Microsoft.

Besides a global high-level view showing the overall health of the cluster (in the style of ping mesh), the dashboard should also:

• display aggregated stats (mean latency, median latency, max latency, ...)
• highlight issues (e.g., is there a Node with multiple ingress / egress links down?)
• enable users to search for / select a specific Node by name and display its measurements

@antoninbas Please assign this issue to me, I will split it into small steps.
