Started reworking `ExternalResourceRepository` so that no network request spans more than one method call on `ExternalResourceRepository` or `ExternalResource`. This is work in progress and this change leaves `ExternalResourceRepository` in an intermediate state between the old and new behaviours. A subsequent change will remove the old behaviours entirely.
The semantics of the `ExternalResourceDownloadBuildOperationType` have changed in several ways:
- The build operation wraps the entire network request, rather than the "download" portion of the request. - The build operation events are fired regardless of whether the network request was successful or not. - No content type or content length are included in the operation's detail.
This build operation type is yet to be refactored or documented to reflect these changes.
