Add yang model definition for CHASSIS_MODULE table (#14007)

Browse Source 
Why I did it
Add yang model definition for CHASSIS_MODULE define and implemented for sonic chassis. HLD for this configuration is included in https://github.com/sonic-net/SONiC/blob/master/doc/pmon/pmon-chassis-design.md#configuration

Fixes #12640

How I did it
Added yang model definition, unit tests, sample config and documentation for the table

How to verify it
Validated config tree generation using "pyang -Vf tree -p /usr/local/share/yang/modules/ietf ./yang-models/sonic-voq-inband-interface.yang"

Built the below python-wheels to validate unit tests and other changes

### Chassis Module
CHASSIS_MODULE table holds the list and configuration of linecard and fabric modules in a SONiC chassis.
It currently allows user to administratively bring down a line-card or fabric-card
```
{
"CHASSIS_MODULE": {
"LINE-CARD0": {
"admin_status": "down"
},
"FABRIC-CARD1": {
"admin_status": "down"
