[COPP:Yang-changes] Fix for config replace issues seen with COPP configurations

[Verma-Anukul]

==> Issue: config replace/yang-validation fails for COPP configurations.

==> Root cause: • COPP's device initial config copp_cfg.json has missing yang mandatory leaf "trap_action" for "default" COPP_GROUP. • "genetlink_name" & "genetlink_mcgrp_name" nodes are not added in sonic-copp.yang, which are used for "queue2_group1" in copp_cfg.json

==> Fix: • In copp_cfg.json, mandatory leaf "trap_action" is added for "default" COPP_GROUP.

"COPP_GROUP": { "default": {

• "trap_action":"trap", <<< this node needs to be added "queue": "0", "meter_type":"packets",

• "genetlink_name" and "genetlink_mcgrp_name" leaves are added in sonic-copp.yang.

• DB Migration script is updated to upgrade the DB config automatically.

==> Tests : Config replace -> i. Config load copp_cfg.json ii. Config save iii. Config replace -> Ensure no error seen

Upgrade -> i. Save config in build without the fix ii. upgrade to build with changes and ensure configurations are reflected in new config_db.json
