features:
  - |
    Add glance::api::enabled_backends and glance::api::default_backend
    parameters for configuring glance backends. The parameters implement
    glance's Multi Store syntax, which supports configuring multiple backends
    of the same type (e.g. multiple rbd backends). Multiple backends of the
    same type may be specified using new glance::backend::multistore::*
    defined resource types.
deprecations:
  - |
    The following parameters are deprecated due to the corresponding parameters
    being deprecated in glance. They are replaced by the new
    glance::api::enabled_backends and glance::api::default_backend parameters.
    * glance::api::stores
    * glance::api::default_store
    * glance::api::multi_store

    The following backend resources are deprecated because they are associated
    with the deprecated glance::api::stores parameter. They are replaced by
    corresponding glance::backend::multistore resources, except for the s3
    backend which was removed from glance in Newton.
    * glance::backend::cinder
    * glance::backend::file
    * glance::backend::rbd
    * glance::backend::s3
    * glance::backend::swift
    * glance::backend::vsphere
