Support clone_image from Glance cinder backend | This adds an implementation of clone_image which offloads the image copy when the image is stored in Glance Cinder backend. It uses "create_clone_volume" method to create a new volume from an image that is placed on a cinder volume. In addition, if use_cinder_backend_for_image_upload is set to True, upload-to-image in raw format will create a cloned volume and register its location to the image service. This enables volume data copy offloading (or CoW) from/to Glance images. Also useful for sharing volume data using Glance ACL feature. |

generic-volume-migration | Currently, cinder supports these 3ways for volume migration. - Cinder storage driver - Cinder volume manager - Nova compute The purpose of this bluprint is introduce a mechanism to handle sparse copy option properly into Cinder assisted volume migration. This patch changes the generic volume migration logic to support non-attachable volumes. |

capacity-headroom | The proposol calculates virtual free capacity for pool and sum total for the backend which support thin provisioning. It will then notify various capacity info to ceilometer service. |

Incremental backup improvements for L | Incremental backup improvements for L 1. Add 'is_incremental=True' and 'has_dependent_backups=True/False' to response body of querying. 2. Add parent_id to notification system. Since we need to get volume has_dependent_backups value when querying volume detail list, to reduce the performance impact, add index to parent_id column in backup table. |

support-import-export-snapshots | Currently cinder support import/export volume function. Import/export snapshots function could be an complement for the function of import/export volume. Implement function to manage/unmanage snapshots 1. Add snapshots manage action in contrib api and unmanage action in API extension. 2. Implement manage_existing_snapshot in manager and flow to import existing snapshots. 3. Add manage/unmanage support in the LVM driver |

Add pagination to snapshots | Add pagination to snapshots Currently snapshot list does not provide pagination like volume does. This patch adds pagination for snapshots in the same way that volume does, using marker, limit, sort_keys and sort_dirs. |
