DEBUG DUMP UTIL PR SEQ: 4

NOTE: PLEASE MERGE #1668 BEFORE MERGING THIS

What I did

HLD for Dump Utility: HLD.
For More info on Tech Support Addition: TechSupport

How I did it

Module Names are retrieved by parsing the output of dump state --show command.

Eg:

root@sonic:~# dump state  --help
Usage: dump state [OPTIONS] MODULE IDENTIFIER

  Dump the redis-state of the identifier for the module specified

Options:
............
 -s, --show            Display Modules Available
............

root@sonic:~$ dump state --show
Module    Identifier
--------  ------------
copp      trap_id
port      port_name

How to verify it

root@sonic-dev:~# show techsupport --debug-dump
root@sonic-dev:~# tar -xvzf /var/dump/sonic_dump_sonic-dev-69_20210525_055031.tar.gz
