==> Issue:
• Config replace/yang-validation fails for SNMP contact configuration.
• In SNMP contact CLI, email field is mandatory
Related to sonic-net/sonic-buildimage#12620
==> Root Cause:
• sonic-snmp.yang defines leaf Contact, but sonic-utilities (CLI backend) writes to ConfigDB with key {contact_name}. So YANG validation fails when the key is {contact_name} and not the string "Contact"
• CLI current implementation is expecting two mandatory arguments
==> Fix:
• sonic-utilities (CLI backend) code is updated to use Yang leaf name "Contact" string as key and user passed input as "value"
• CLI implementation (sonic-utilities) is changed to expect only a single string, where user can pass any string of choice (name, email, phone, address or combination of these). Accordingly, "show" CLIs will display only "contact" instead of "name" & "email"
Migration script is updated to take care of config_db migration
Tests:
Test CLIs manually
Test config replace
Test config migration
