    Basic container quotas
    
    Add a new middleware implementing some basic container quotas.
    
    Quotas are subject to several limiations: eventual consistency, the timeliness
    of the cached container_info (60 second ttl by default), and it’s unable to
    reject chunked transfer uploads that exceed the quota (though once the quota
    is exceeded, new chunked transfers will be refused).
    
    However, they get most of the way to container quotas fairly inexpensively.
    
    Quotas are set by adding meta values to the container, and are validated when
    set:
    
      X-Container-Meta-Quota-Bytes: Maximum size of the container, in bytes.
      X-Container-Meta-Quota-Count: Maximum object count of the container.
