Console applications revision

• I've done Console applications should participate to the main host builder #5006 for https://github.com/abpframework/abp/tree/dev/templates/console Please apply to the app/module startup templates
• Delete the https://github.com/abpframework/abp-samples/tree/master/BasicConsoleApplication because it is no longer needed. We can create the same via console template.
• Change https://docs.abp.io/en/abp/latest/Getting-Started-Console-Application to show how to use the abp cli and the console template to create the application. No need to show how to create manually.

It it good for console application.But I think there may be more than one service in a project. Execute Application.Initialize in IHostedService is a bit strange to me. I think we can execute Application.Initialize before the host starts.

I agree. I will create a new issue to improve this further.
