ClientModel: Give PipelinePolicies a DefaultPosition

Feature request

I would like policies to have the following property:

public PipelinePosition DefaultPosition { get; }

In addition, all APIs that take a policy and the position (e.g. Add(PipelInePolisy, PipelinePosition) should default the second parameter. This would allow adding policies without having to specify the position (which users often don't know what it should be),

This is to support RestClient scenarios.

In addition, this change should address

Per conversation with @KrzysztofCwalina, this would be additive, so moving to a later milestone.
