    Update os_compute_api:os-flavor-extra-specs:index docs for 2.47

    The 2.47 compute API relies on policy rule
    os_compute_api:os-flavor-extra-specs:index to determine
    if flavor extra specs should be shown in the embedded flavor
    response when showing server details, updating a server or
    rebuilding a server. This change updates the documentation
    for the policy rule to indicate its usage in those APIs.
