Revert "Swift: configure Ceilometer when it is enabled"

This reverts commit f208aafa35996c98de40c1388bbebf326ab2ed20. This
commit broke swift functional tests because the ceilometer middleware
changes HTTP 404 responses into zero byte responses. This results in
BadStatusLine exceptions. Back out the use of ceilometer middleware
until it can be fixed.
