Scheduling backups of Cinder volumes using centralized instance(s) of freezer-scheduler requires executing tasks on behalf of the user. Client capabilities provide a mechanism to restrict which actions, modes, storages, and engines can be assigned to freezer-scheduler for security and workload control. The core implementation of client capabilities resides in freezer-scheduler. The primary purpose of checking capabilities on the freezer-api side is to prevent the assignment of actions that cannot be executed by a specific scheduler instance. Implements: blueprint centralized-scheduler Depends-On: I15a91e8232d07e5bbc2cc95a72b0405c61c64a72 Change-Id: Ie774f9e66ac373a43ef935775de3b18539c5bebd
