Cinder supports filter volumes with metadata, but in some case, users don't know what metadata the volumes contain or what metadata is valid to filter volumes. This patch updated volumes/summary API to return all valid distinct metadata to users. Then users could use these metadatas to filter volumes easily. This function is useful for dashboard, such as Horizon, as well. APIImpact Implements: blueprint metadata-for-volume-summary Change-Id: I33c77d9db88f70d8d3b8ea86c86c01220dcc537c
