Issue 1749 - OData V4 service do not properly handle invalid
OData-Version header values (V3 version)
https://aspnetwebstack.codeplex.com/workitem/1749

This fix adds a version constraint to the ODataRoute that will prevent
it from matching any request with a v4 version header or a request with
a v1-v3 version header whose value is outside of the range of this
constraint. The default range for the constraint is 1.0 to 3.0, but this
can be changed by removing the constraint and adding a different one
with a different range. This constraint will still match any request
without version headers.
