Basic container quotas

Browse Source 
Add a new middleware implementing some basic container quotas.

Quotas are subject to several limitations: 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.
