Some small changes to work with akamai.  Stress_test script is modification of test_running_server that hits 2 ct instances to see if they communicate properly.
Harmonizing some naming conventions.  No real functionality changes.
Max DB entry size should revert to DB limit if config set back to 0. Also fixed a problem that a peer was appearing as removed and active after I rand the removed peer removal from the db_tool.  Modified code to only remove the indexes of peers who appear only in removed as a safety check.  All removed peers get taken out of list though after done.  Not sure why it happened.
