Implemented a new feature to configure the pattern used for generating endpoint routes in domain services

The `AddDomainService(Type type)` method was modified to use the new `GetDomainServiceRoute(type)` method.

A new file `DomainServiceEndpointRoutePatternAttribute.cs` was added, defining the `EndpointRoutePattern` enum and the `DomainServiceEndpointRoutePatternAttribute` attribute. The `GenerateConstructors()` method in `CSharpDomainContextGenerator.cs` and `CSharpDomainContextGenerator.tt` was modified to use the new `GetDomainServiceUri()` method.

A new method `GetDomainServiceUri()` was added to `CSharpDomainContextGenerator.partial.cs` and `DomainServiceProxyGenerator.cs`. The `ClientCodeGenerationDispatcher.cs` and `ClientCodeGenerationOptions.cs` were modified to load and set the `DefaultEndpointRoutePattern` option. The `DomainServiceProxyGenerator.cs` was modified to use the new `GetDomainServiceUri()` method.

A new file `EndpointRoutePattern.cs` was added, defining the `EndpointRoutePattern` enum. The `Program.cs` was modified to set the `DomainServiceEndpointRoutePattern` attribute for the assembly to `EndpointRoutePattern.WCF`.

Updated the `BinaryHttpDomainClientFactory` class in the `OpenRiaServices.Client.DomainClients` namespace. The `_httpClientFactory` field now accepts a `Uri` parameter for `HttpClient` creation.

Updated `DomainClientFactory` so that it will only append "/binary/" for WCF style Uris, for all other kinds of uri it will ensure there is a trailing "/" instead.

Add special workaround for AspNetCore tests so that they use the "Fullname" endpoint pattern even though the client is generated to use WCF style pattern.

…ests passing
