Increase logging for xenapi plugin glance uploads
Increase logging for xenapi plugin glance uploads

Without this change, the glance plugin is pretty quiet about image
uploads. But it can definitely be helpful to debugging to have
information such as which glance server is handling the upload, how much
data was sent, and more information about the glance server response if
it was something other than 200 OK.
