Support for custom HTTP client handler

Hey.
I build a .NET app where I would like to use docker client, but instead of interacting with docker directly, I want to intercept all REST calls from the sdk, manipulate them, and redirect the request to different service. this can be done by adding some DelegatingHandler to the HTTPClient.
It will really help if there was an option to build DockerClient with custom client / handler.
Plus it is just nice feature in general.
