CLI development changes for PNAC HLD PR 1292

[thovikeerthi]

What I did

Adding CLI development code changes for the feature PNAC as per HLD PR 1292.

How I did it

Added code changes at CLI's 'config' and 'show' module sets to configure and monitor the PNAC feature via SONiC CLI
Code changes at:

• sonic-utilities/config/main.py
• sonic-utilities/show/main.py
• sonic-utilities/show/nac.py

How to verify it

Existing SONiC CLI framework is enhanced to support this new CLI additions and these commands available similar to other command sets.
To verify it,

1. Enter the SONiC CLI
2. Enter into root user mode
3. Run the new NAC CLI commands

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)
