    Raise HTTP exception for backup not found

    If backup cannot be found while resetting its status, Cinder
    exception (BackupNotFound) is raised instead of HTTP exception.
    This patch handles the BackupNotFound exception and raises
    HTTPNotFound exception.

    APIImpact
    HTTPNotFound exception (404) is raised instead of BackupNotFound
    if backup cannot be found during backup reset-status.
