Create and update operations on the camel-olingo2 component use EntityProvider with EntityProviderWriteProperties in order to construct the content data in different data formats (Json, Atom, XML)
At the moment these write properties are not configurable by the user. The Camel component just uses the default settings.
With this default settings in place the Camel component always adds OData metadata to requests by default. This leads to errors when the target OData service (e.g. https://services.odata.org/V2/OData/OData.svc/) does not support metadata being added to the request.
The EntityProviderWriteProperties has options to enable "contentOnly" settings for these kind of OData services. Users need to be able to set these write properties on the endpoint configuration.
