Description
Durign presanity recovery, when recovery is triggered with golden_config, config reloads command fails for multi-asics system.

https://github.com/sonic-net/sonic-mgmt/blob/master/tests/common/config_reload.py#L130

During sonic-mgmgt tests, if sanity precheck fails, the scripts try to recover the setup by executing ‘config reload’ with running_golden_config files saved.

the command executed is 'config reload -f -l /etc/sonic/running_golden_config.json'

This command works fine on single asic systems but does not work on multi-asic cards.

For multi asic cards, the config reload expects one global config file and one namespace config file for each namespace:

e.g: for 2 asic LC:

config reload -f -l /etc/sonic/running_golden_config.json,/etc/sonic/running_golden_config0.json,/etc/sonic/running_golden_config2.json
