After onie install with latest sonic-utilities configuration is not loaded into CONFIG_DB resulting in failure to initialize switch

[dgsudharsan]

Description

Issue due to yang validation introduced in the PR https://github.com/sonic-net/sonic-utilities/pull/3576

The config-setup generates a configuration which is not yang aligned. For example loopback and interface tables are defined like below

    "LOOPBACK_INTERFACE": {
        "Loopback0|10.1.0.1/32": {}
    },
   "INTERFACE": {
        "Ethernet0|10.0.0.0/31": {},

While yang expects it to

    "LOOPBACK_INTERFACE": {
        "Loopback0": {},
        "Loopback0|10.1.0.1/32": {}
    },
    "INTERFACE": {
        "Ethernet0": {},
        "Ethernet0|10.0.0.0/31": {},

@qiluo-msft @wen587 Can you please prioritize this as this is a regression issue?

[qiluo-msft]

@wen587 , seems "factory default configuration" fails yang validation.

@dgsudharsan Could you share the /etc/sonic/config_db.json when issue happens?
