Ceph RESTful API

RESTful API exposed by the Ceph Manager dashboard module for managing and monitoring a Ceph cluster, including pools, OSDs, hosts, monitors, RGW, RBD, CephFS, users, and cluster configuration. Authentication uses a JWT obtained from /api/auth, and versioning is negotiated via the Accept header (application/vnd.ceph.api.v{major}.{minor}+json).
