Enable OData Client to make V4.01 requests

[KenitoInc]

OData Client seems to make V4 requests only. It would be great to allow it to make V4.01 requests, unless this will break existing logic.

A few specific areas in the code where V4 is hardcoded: https://github.com/OData/odata.net/blob/82eb2b27219103ac22bdde9eb634eebf0ce99f52/src/Microsoft.OData.Client/DataServiceContext.cs#L3598 https://github.com/OData/odata.net/blob/82eb2b27219103ac22bdde9eb634eebf0ce99f52/src/Microsoft.OData.Client/ALinq/ResourceBinder.cs#L1715 https://github.com/OData/odata.net/blob/82eb2b27219103ac22bdde9eb634eebf0ce99f52/src/Microsoft.OData.Client/DataServiceRequest.cs#L198
