grizzly: swift container quotas

[Tom Fifield]

If merged, https://review.openstack.org/#/c/18124/ will introduce a new feature to swift: 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.

   17 The ``container_quotas`` middleware implements simple quotas that can be
   18 imposed on swift containers by a user with the ability to set container
   19 metadata, most likely the account administrator. This can be useful for
   20 limiting the scope of containers that are delegated to non-admin users, exposed
   21 to ``formpost`` uploads, or just as a self-imposed sanity check.
   22
   23 Any object PUT operations that exceed these quotas return a 413 response
   24 (request entity too large) with a descriptive body.
   25
   26 Quotas are subject to several limitations: eventual consistency, the timeliness
   27 of the cached container_info (60 second ttl by default), and it's unable to
   28 reject chunked transfer uploads that exceed the quota (though once the quota
   29 is exceeded, new chunked transfers will be refused).

   31 Quotas are set by adding meta values to the container, and are validated when
   32 set:

   35 |Metadata | Use |

   37 | X-Container-Meta-Quota-Bytes | Maximum size of the |
