[gpunathilell]

What I did

To add initializeGlobalConfig for dump command in case of multi asic implementation, This si to prevent the error:

root@dut:/home/admin# dump state interface Ethernet0 -n asic0
Traceback (most recent call last):

RuntimeError: :- validateNamespace: Initialize global DB config using API SonicDBConfig::initializeGlobalConfig

On multi asic system

How I did it

Initializae global config

How to verify it

Run unit test

Previous command output (if the output of a command-line utility has changed)

New command output (if the output of a command-line utility has changed)
