Need ManualCredential option in OData.Feed function

[gsingh395]

We are trying to build a custom connector that wraps OData feed function. The connector provides API key as one of the authentication methods.

We want to inject API key in a custom header but by default mashup engine inserts API key in an authorization header as if this value were a basic auth password.

Web.Contents function provides ManualCredential option that instructs mashup engine to not insert API key in authorization header and we need that for OData.Feed function as well.
