Almost got the multi-ec2 experiment deployment working. Had to handle
several hiccups.
* added a small test param config called 'tiny'
* refactored deploy.py a bit to get rid of older little used and unused functions
* created AWSConsumer subclass of JobConsumer instead of bloating JobConsumer
* change 'run' to point to the same deployment structure as 'batch'
* made commandline parameter generation more automatic
* created small script clear_logs.py
