Improve Support for Custom OData Conventions

[commonsensesoftware]

Overview

It is currently possible, but quite difficult, to add custom OData route conventions. API versioning adds its own conventions which makes adding or change route conventions require a significant amount of setup.

Feature

Improve the setup methods afforded by the various MapVersionedODataRoute to include support for adding or changing custom OData route conventions. This should not require duplicating or changing the entire container setup.
