Sam,

You might find cloud-init (https://launchpad.net/cloud-init) useful. It is
a tool (project also run by Scott Moser) to perform all kinds of instance
bootstrapping upon being launched, rebooted, etc across various operating
systems as well as cloud providers.  Specific to your case, cloud-init
supports growing any number of partitions. Here is an example of the
configuration:
https://github.com/number5/cloud-init/blob/master/doc/examples/cloud-config-growpart.txt

And more info on using cloud-init itself:
http://cloudinit.readthedocs.org/en/latest/

Hope this helps,
Craig
