HttpPatch Header Options to return patched object

[awdorrin]

Currently a successful patch only returns a success response. A method to provide the Http header options to return a full object would be very helpful in certain circumstances. (ie. PatchWithReturn().Exec() ?)

Otherwise, a way to set the HttpHeaders manually would be useful. I don't see a public method for setting headers, only the protected 'getPostRequestOptions'

Thank you
