In modular chassis, add CHASSIS_STATE_DB on control card (#5624)
HLD: Azure/SONiC#646

In modular chassis, add CHASSIS_STATE_DB on control card

Why I did it
Modular Chassis has control-cards, line-cards and fabric-cards along with other peripherals. Control-Card CHASSIS_STATE_DB will be the central DB to maintain any state information of cards that is accessible to control-card/

How I did it
Adding another DB on an existing REDIS instance running on port 6380.
