So, the actual bug is invalid, there is clearly a bug in the side effect
though, which is it throwing 500.

The node_staging_uri is used as local cache for the taskflow to store
the data it downloads before the rest of the tasks are ran. So it is
needed for the 'web-download' (In 'web-download' only use case it does
not need to be shared between the glance nodes). If the methods are
incorrectly configured, the image should stay in 'queued' but we should
fail the import call gracefully.

Title:
  Image remains in queued state for web-download if node_staging_uri is
  not set

Status in Glance:
  Invalid

Bug description:
  If operator does not set 'node_staging_uri' in glance-api.conf then
  importing image using web-download remains in queued state.

  Steps to reproduce:
  1. Ensure glance-api is running under mod_wsgi (add WSGI_MODE=mod_wsgi in local.conf and run stack.sh)
  2. Do not set node_staging_uri in glance-api.conf

  3. Create image using below curl command:
  curl -i -X POST -H "x-auth-token: <auth-token>" http://192.168.0.13:9292/v2/images -d '{"container_format":"bare","disk_format":"raw","name":"Import web-download"}'

  4. Import image using below curl command:
  curl -i -X POST -H "Content-type: application/json" -H "x-auth-token: <auth-token>" http://192.168.0.13:9292/v2/images/<id-of-image-created-in-step-3>/import -d '{"method":{"name":"web-download","uri":"https://www.openstack.org/assets/openstack-logo/2016R/OpenStack-Logo-Horizontal.eps.zip"}}'

  Expected result:
  Image should be in active state.

  Actual result:
  Image remains in queued state.
