InferMappingFor.Ignore for inherited property

[Grastveit]

NEST/Elasticsearch.Net version: 5.0.1 (and also in 2.4)

Elasticsearch version: 5.1.2

Description of the problem including expected versus actual behavior:

I'd like to ignore an inherited property without using attributes. InferMappingFor is the other option then, however I'm only able to ignore declared properties.

Steps to reproduce:

The snippet below makes a mapping with a single inheritedProp-field, instead of no fields, as I expected.

void Main()
{
	new ElasticClient(new ConnectionSettings(new Uri("http://localhost:9200"))
		.InferMappingFor<Foo>(i => i
			.Ignore(f => f.InheritedProp)
			.Ignore(f => f.DeclaredProp))
	).CreateIndex("fooindex", c => c.Settings(s => s.NumberOfShards(1).NumberOfReplicas(0))
		.Mappings(ms => ms.Map<Foo>(m => m.AutoMap()))
	);
}

public class FooBase
{
	public int InheritedProp { get; set; }
}

public class Foo : FooBase
{
	public int DeclaredProp { get; set; }
}

I also unsuccessfully tried InferMappingFor<FooBase>.

I agree this is unexpected:

At the time AutoMap() reflects the properties we have no ConnectionSettings to check against so this is by design.

I've added #2560 though so that when Properties are written we double check against ConnectionSettings

Thanks for opening this one @Grastveit 👍

Jotting this down for future googlers: programmatically ignoring/renaming base properties for serialization on connection settings works fine
