add cloud-init-run-module and ec2init/execute.py

cloud-init-run-module handles some boilerplate code for running
items on a 'frequency'.  It has the following usefulness

- a config module can be put into ec2init dir and implement a 'run'
  method that takes a list of arguments and the path to a config file
- it handles invoking module.run() only at a given frequency
  This is similar to karmic's ec2init's "run_once_ever" or run_once_per_ami

execute.py is an example module that executes the arguments given to it

An example usage in an upstart job would be with a 'exec' line like:

   exec cloud-init-run-module once_per_ami clean-core execute rm /var/run/core

The above would then run the command 'rm /var/run/core' only once
