Abstract Presentation.Web related extension methods

[wintondeshong]

There are a few key extension methods we heavily use across projects that could be extracted into the AndcultureCode.CSharp.Web package.

• IApplicationBuilderExtensions#ConfigureSeedData
• ModelStateExtensions
• AuthorizationFilterContextExtensions
• IServiceCollectionExtensions.AddAndcultureCodeLocalization
• IServiceCollectionExtensions.AddMiddleware -> make a more specific optional AddRequestThrottling that allows a project to 'enable' rate limiting functionality. Should not remain as generic AddMiddleware
• IServiceCollectionExtensions.ConfigureRequestLocalizationOptions
• IServiceCollectionExtensions.ConfigureRewriteOptions - Should be either bundled with another similarily named or pulled into its own that spells out what rewrite options it is configuring. Not kept generic
• IServiceCollectionExtensions.ConfigureRouteOptions - Same as above, should be grouped with similar and explicitly named functionality around localization
• IServiceCollectionExtensions.ConfigureForwardedHeaders - fixed by New controller interfaces and Cookie Auth handling AndcultureCode.CSharp.Web#6
