Implement containers for heat-engine and heat-api

Loosely followed this document for setting up Heat:
http://docs.openstack.org/icehouse/install-guide/install/yum/content/heat-install.html

Some gotchas:
- crux doesn't require escaping parenthesis for endpoint creation like
  keystone client
- heat icehouse packages are configured for qpid, so kombu had to be
  specified specifically

This firewall reference was handy for port information:
http://docs.openstack.org/trunk/config-reference/content/firewalls-default-ports.html

Implements: blueprint kube-heat-container
