Rally cleanup script fix

This patch introduces the following changes.
1. rally_cleanup.py has been moved to the utils directory.
2. The rally_cleanup.py script was getting stuck in an infinite loop
as some functions were modified to clean up only rally objects while
other functions were not modified. This patch modifies the first function
that is called in traceback to clean up only rally objects, to avoid such
issues.
