[Err msg]ERR python: :- initializeGlobalConfig: Sonic database config global file doesn't exist at /var/run/redis/sonic-db/database_global.json

Description

Steps to reproduce the issue:

1. Deploy the 202211 image, and load the config with minigraph
2. execute the log analyzer.

Describe the results you received: Could see the following err msg in the syslog ERR python: :- initializeGlobalConfig: Sonic database config global file doesn't exist at /var/run/redis/sonic-db/database_global.json

Have debug the issue with design team, it seems the issue will happen on the non multi-asic system, but it is a statistic issue (don't understand why it is statistic) In ansible/library/switch_capabilities_facts.py:

class SwitchCapabilityModule(object):
    def __init__(self):
        self.module = AnsibleModule(
            argument_spec=dict(
            ),
            supports_check_mode=True)

        self.out = None
        self.facts = {}

        return

    def run(self):
        """
            Main method of the class
        """
        self.facts['switch_capabilities'] = {}
        namespace_list = multi_asic.get_namespace_list()

        SonicDBConfig.load_sonic_global_db_config()
        conn = SonicV2Connector(namespace=namespace_list[0])
        conn.connect(conn.STATE_DB)
        keys = conn.keys(conn.STATE_DB, 'SWITCH_CAPABILITY|*')

        for key in keys:
            capab = conn.get_all(conn.STATE_DB, key)
            self.facts['switch_capabilities'][key.split('|')[-1]] = capab

        self.module.exit_json(ansible_facts=self.facts)

but SonicDBConfig.load_sonic_global_db_config() seems could only work for the multi-asic system.

And also in the ansible/module_utils/multi_asic_utils.py, I see different implement for multi-asic and non multi-asic system:

        if multi_asic.is_multi_asic():
            if not swsscommon.SonicDBConfig.isGlobalInit():
                swsscommon.SonicDBConfig.load_sonic_global_db_config()
        else:
            if not swsscommon.SonicDBConfig.isInit():
                swsscommon.SonicDBConfig.load_sonic_db_config()

So maybe we also need to update the code in the ansible/library/switch_capabilities_facts.py to be applicable to both multi and non-multi asic system to aviod the issue

Here is how load_sonic_global_db_config is implemented:

void SonicDBConfig::initializeGlobalConfig(const string &file, const string &ns, const string &call_mod)
{
    std::string local_file, dir_name, ns_name;
    std::unordered_map<std::string, SonicDBInfo> db_entry;
    std::map<std::string, RedisInstInfo> inst_entry;
    std::unordered_map<int, std::string> separator_entry;
    std::lock_guard<std::recursive_mutex> guard(m_db_info_mutex);

    SWSS_LOG_ENTER();
    SWSS_LOG_NOTICE("enter SonicDBConfig initializeGlobalConfig");

    if (m_global_init)
    {
        SWSS_LOG_ERROR("SonicDBConfig Global config is already initialized");
        return;
    }

    ifstream i(file);
    if (i.good())
    {
        local_file = dir_name = std::string();

...

    }
    else
    {
        if (ns.empty())
        {
            SWSS_LOG_ERROR("Sonic database config global file doesn't exist at %s ns empty call mod %s", file.c_str(), call_mod.c_str());
        }
        else
        {
            SWSS_LOG_ERROR("Sonic database config global file doesn't exist at %s ns %s call mod %s\n", file.c_str(), ns.c_str(), call_mod.c_str());
        }
    }

    // Set it as the global config file is already parsed and init done.
    m_global_init = true;
}

Describe the results you expected: No such err msg
