make cloud-config modules configurable by cloud-config

The list of cloud-config modules is now kept in cloud config itself.
There is a builtin list in cloudinit, which is overrideable by 
 /etc/cloud/cloud.cfg or user data cloud-config.

This should make the modules more easily added or removed (as no code
needs to be edited now)

Basic summary of changes:
 - move CloudConfig.py -> cloudinit/CloudConfig/__init__.py
 - split cloud-config modules into their own files named
   cloudinit/CloudConfig/cc_<name>.py
 - remove all the upstart/cloud-config-* scripts, replacing them with
   upstart/cloud-config.conf
