modified update_pushlog command to use pid strategy

This branch modifies the existing `update_pushlog` command to utilize a pid strategy to send a `kill -9 pid` if it's detected in the process list when it's run. All termination events are logged to a log file, this is a work around for a bug in python's urllib which causes the program to hang when there is an interrupt in an HTTP GET. This branch also contains a fix for a long standing bug in the `datazilla/webapp/apps/datazilla/views.py set_test_data()` method returning a web service endpoint with a 0 id in it.
