Public bug reported:

Glance added the support for interoperable image imports. Image uploads are done using a two-step approach:
first uploading it to the Glance API using a local staging area, and then triggering an upload from the staging area to the storage backend.

In the case of an HA setup (ie with 3 controller nodes) this requires a
shared consistent filesystem across the controller nodes. Otherwise it
might happen that the image is uploaded to one node, and triggering the
import is executed on a different node - where the image does not exist.

Therefore we need to remove 'glance-direct' from the default, thus
operators need to enable it explicitly if they have a shared filesystem
across the controller nodes (for example using NFS).
