SONiC Yang model support for Kdump (#10786)

Browse Source 
#### Why I did it
Created SONiC Yang model for Kdump
Tables: KDUMP

#### How I did it
Defined Yang models for NAT based on Guideline doc:
https://github.com/Azure/SONiC/blob/master/doc/mgmt/SONiC_YANG_Model_Guidelines.md
and
https://github.com/Azure/sonic-utilities/blob/master/doc/Command-Reference.md

#### How to verify it
Added test cases to verify it.
