The ApiClient does allow for custom serialization

[zacrumford]

See this line for details.

There is no way to supply a custom serializer in ApiClient. While there exists the 'serializerSettings' member, there are two issues with this:

1. this is not use as input to JsonConvert.Serialize() during serialization
2. the serializerSettings member is private and there is no way of setting it in a constructor.

Additionally, one would think that ApiClient.RestClient.UseSerializer<T> (or the Newtonsoft extension UseNewtonsoftJson) would have an effect but this is completely unused in ApiClient.

Proposed fixes:

1. Add a ctor to allow overload for serialization settings and use that.
2. Use the serializer in the RestClient

Note: callers can work around this by configuring newtonsoft's default serializer options but this is error prone and affects the whole process.
