Current glance command does not show the details of error message.
For example, the glance command shows HTTPBadRequest only if some
necessary parameter is not specified.
$ glance image-create --file root-fs.img --name cirros-0.3.0-x86_64-uec
Request returned failure status.
HTTPBadRequest (HTTP 400)
$
By only the above message, it is not easy that a user understand the reason
of an error. glance-api server returns the details of reason, but glance
command does not show it.
This patch adds details, which is gotten from glance-api server, to error
message. And a user will be able to understand the reason of a error like
the following:
$ glance image-create --file root-fs.img --name cirros-0.3.0-x86_64-uec
Request returned failure status.
400 Bad Request
Invalid disk format 'None' for image.
(HTTP 400)
