Public bug reported:

Newly added multiple import fails if user passes "all_stores" as "true" in the request.
The reason is if all_stores is specified then we are getting stores using CONF.enabled_backends and unfortunately we are injecting reserved stores 'os_glance_staging_store' and 'os_glance_tasks_store' runtime. As a result import job tries to import the image in the 'os_glance_staging_store' store as well where it fails as that image is already staged in this staging store.

Steps to reproduce:

1. Create image using
   glance --debug image-create-via-import --disk-format qcow2 --container-format bare --name multi-copy-test-13
2. Stage the data for import using
   glance image-stage <image-id> --file <file-name>
3. import image in multiple stores by setting all_stores as true
   curl -g -i -X POST http://192.168.0.27:9292/v2/images/<img-id>/import "User-Agent: python-glanceclient" -H "Content-Type: application/json" -H "X-Auth-Token: <token>" -d '{"method": {"name": "glance-direct"}, "all_stores": "true"}'


Expected result:
Image should be imported in all stores configured using enabled_backends config option

Actual result:
Image fails to import and data remains in staging area

Possible solution:
After population stores using CONF.enabled_backends, remove reserved stores from those stores.
