Thumbnail feature SHOULD be optional (module chooser) + configuration of the thumbnail URL

[vttranlina]

How

• DISABLE by default
• The configuration will be provided in thumbnail.properties
  • enable: true|false
  • url: Optional. Require when enable is true
• Use Guice Module to install instance dependencies
• Configuration class: ThumbnailModuleChooserConfiguration.java

public record ThumbnailModuleChooserConfiguration(boolean enable, Optional<URL> url) {
    public static ThumbnailModuleChooserConfiguration parse(PropertiesProvider propertiesProvider) throws ConfigurationException {
        try {
            Configuration configuration = propertiesProvider.getConfiguration("thumbnail");
            boolean enable = configuration.getBoolean("enable", false);
            Optional<URL> urlOptional = Optional.ofNullable(configuration.getString("url", null))
                .map(Throwing.function(URL::new));
            if (enable) {
                Preconditions.checkArgument(urlOptional.isPresent(), "url is required");
            }
            return new ThumbnailModuleChooserConfiguration(enable, urlOptional);
        } catch (FileNotFoundException e) {
            return new ThumbnailModuleChooserConfiguration(false, Optional.empty());
        }
    }
}

Dod

• Integration test, the thumbnail capability should be advertising in the session route when enabled
