Swift proxy performance fixes

Browse Source 
Performance testing of an OSA deployed Swift cluster hit several issues.
Comparison of the proxy conf with the Swift Auth docu [1] found
two settings that affect performance that that were not set in the template.

include_service_catalog - This defaults to True which makes the proxy server
fetch the service catalog on every request in the authtoken middleware. This
hammers Keystone.

cache - When using memcache this should be set so the authtoken middleware
uses the correct cache and not go back to Keystone on every request.
