Secure user data - remove AuthorizeFolder/AuthorizePage

[Rick-Anderson]

1. Replace SSL with HTTPS.
2. Once the default authorization is set requiring the user to be authenticated, no longer need the following:

services.AddMvc();
        //.AddRazorPagesOptions(options =>
        //{
        //    options.Conventions.AuthorizeFolder("/Account/Manage");
        //    options.Conventions.AuthorizePage("/Account/Logout");
        //});
