[Bug]: [202405][multi-asic] test_passw_hardening.py fails with: libyang[0]: Missing required element \"lanes\" in \"PORT_LIST\"

Issue Description

When running test_passw_hardening.py on a multi-asic system it will try to run sudo config passw-hardening policies expiration 100 in the global netns which fails with the following lines:

> sudo config passw-hardening policies expiration 100
libyang[0]: Missing required element "lanes" in "PORT_LIST". (path: /sonic-port:sonic-port/PORT/PORT_LIST[name='Ethernet1/1'])
sonic_yang(3):Data Loading Failed:Missing required element "lanes" in "PORT_LIST".
Data Loading Failed
Missing required element "lanes" in "PORT_LIST".
Error: Failed to validate configuration: ConfigMgmt Class creation failed
Aborted!

Here is where that error is emitted:
https://github.com/sonic-net/sonic-utilities/blob/2cb8cc65b6dc57d9613ce271a681743aa4fa0f3c/config/plugins/sonic-passwh_yang.py#L35

I think the problem is it's expecting ports in that namespace but because all the ports are in the per-asic namespace there won't be any in the global namespace.

If I run this same command in the asic namespace it passes:

> sonic-netns-exec asic0 sudo config passw-hardening policies expiration 100

And I can see it update the config_db in the asic namespace:

> sonic-db-cli -n asic0 CONFIG_DB hgetall "PASSW_HARDENING|POLICIES"
{'digits_class': 'true', 'expiration': '100', 'expiration_warning': '15', 'history_cnt': '10', 'len_min': '8', 'lower_class': 'true', 'reject_user_passw_match': 'true', 'special_class': 'true', 'state': 'disabled', 'upper_class': 'true'}

The question I'm unsure of is if we can just change this test to run all the commands in the asic namespace or the yang model needs to be fixed to allow this command to run in the global namespace.

Is it platform specific

generic

@arlakshm is this the same yang model issue you saw with passw_hardening?
