Glance Add Image API returns 400 response if storage is inaccessible

[Unmesh Gurjar]

Glance Add Image API returns 400 response if storage is inaccessible or insufficient permissions in accessing the image store. The API should return an Internal Server Error(500) response instead.

I tend to think that 500 Internal Server Error should be returned only when a server is entirely broken. I'm thinking that 503 Service Unavailable may be a better code to return...

Yep, I'm with Jay.
