could we have a missing localization handler?

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

When I saw a lot of log entries for missing localization items like below:
"JsonStringLocalizer" searched for '"No data found."' in '"XXX.UIStrings"' with culture '"zh-CN"' not found.

I want to add those items. However, it's not easy to find all the missing items from the log. Could we have a IMissingLocalizationHandler which would handle those missing items. for example: I can use it to write the missing items into a temp json file. Then I can add these items in the json file to existing localization json files or resx files.

Describe the solution you'd like

in JsonStringLocalizer.cs

    private void LogSearchedLocation(string name)
    {
        _missingLocalizationHandler.HandleMissingLocalizationItem(name, typeName, CultureInfo.CurrentUICulture.Name);
        if (!ignoreLocalizerMissing)
        {
            Logger.LogInformation("{JsonStringLocalizerName} searched for '{Name}' in '{TypeName}' with culture '{CultureName}' not found.", nameof(JsonStringLocalizer), name, typeName, CultureInfo.CurrentUICulture.Name);
        }
    }

there could be an NullMissingLocalizationHanlder, which does nothing.
