new dashboard for ESS NVME and Hybrid models

[olafWW]

common metrics for ESS (pair or shared recoverygroup)

block:
-- all or selected pdisk IOPS, bandwidth
-- Declusted Array (DA) wise IOPS , bandwidth == total sum of IOPS/BW all(or selected) vdisk(NSD) from a DA
-- all vdisk of an ESS (building block)== total IOPS, bandwidth

network:
-- read /write .. in /out pkts and bandwidth - Ethernet
-- read /write .. in /out pkts and bandwidth - RoCE (Rdma o Ethernet)
-- read /write .. in /out pkts and bandwidth - Infiniband
