Vagrant Cloud provides support for uploading directly to the backend
storage instead of streaming through Vagrant Cloud. This adds support
for direct to storage uploads and sets it as the default upload method.
A new option has been added to disable this behavior and revert back
to streaming upload via Vagrant Cloud (`no_direct_upload`).
This default for uploading directly to the backend storage also matches
up with changes being added to Vagrant proper for box upload behavior:
hashicorp/vagrant#11916
This change updates the underlying type of VagrantCloudErrors.Errors to match the expected errors response type and adds a simple test to verify the parsing of various error responses.
