Make swift's expirer compatible with gluster-swift

Swift's object expirer in kilo series was incompatible with
gluster-swift. This change does the following:

* Optimizes crawl in account and container server for listing
  requests for containers and tracker objects in gsexpiring volume.

* Enables container server to delete tracker objects from gsexpiring
  volume. Swift's expirer sends request directly to container server
  to remove tracker object entry.

* delete_tracker_object() is now a common utility function that is
  invoked from container server and gluster-swift's object expirer.

* Run functional test to be run against both swift's object expirer
  and gluster-swift's object expirer
