Remove Duplicate dashboards

[Hardikl]

We have 4 dashboards where normal dashboard and details dashboard are having duplicate panels. We want all panels from normal dashboard to be included in the details dashboard, So that normal dashboard could be removed later.

Network:

• Ethernet ports table: send and receive guage don't show proper bar in detail dashboard
  --> Rest all panels are fine

Node:

• Avg latency: detail dashboard is using avg(volume_avg_latency{})/1000 with unit ms where as node page use avg(volume_avg_latency{}) with unit us
  --> Rest all panels are fine

SVM:

• Latency per type and iops per type charts are different
• Avg throughput, avg iops table is not available in detail dashboard(They are same for v3, v4 and v4.1)
  --> Rest all panels are fine

Volume:
--> All panels are fine

After above issues are handled, we will remove the normal dashboard.
