Plugins should be loaded when put into the APP Folder

[bqstony]

Currently the plugins are loaded with the requirement to be referenced in the Program.cs

Reactivate the load of the assemblies to load plugins from the app folder

 .ConfigureServices((hostContext, services) =>
 {
     var plugins = new IPlugin[]
     {
         new NLogLog4TcOutputPlugin(),
         new GraylogLog4TcOutputPlugin(),
         new InfluxDbLog4TcOutputPlugin(),
         new SqlLog4TcOutputPlugin(),
     };

     foreach (var plugin in plugins)
     {
         plugin.ConfigureServices(services, hostContext.Configuration);
     }

     // TODO plugin funktioniert momentan nicht mit dritt-Nugets
     //services
     //    .AddPlugins(GetPluginPath())
     //    // ToDo: Differenziate output / input / ... configuration in PluginBuilder
     //    .AddOutputs(hostContext.Configuration);

     services
         .AddLog4TcAdsLogReceiver()
         .AddLog4TcDispatcher();
 });
